The Sunken World Hiding Under the Water's Surface

"A Frenchman visiting Constantinople (now Istanbul) in the 1500s heard strange stories of locals drawing up fresh water and even fishing from holes in their cellars. Intrigued by these stories and the legends of great underground temples, he decided to explore.  Upon further investigation, he found a subterranean marvel, the largest of the long-forgotten palatial cisterns of the Byzantine Empire. Fish swam in an artificial freshwater lake the size of two football fields and the vaulted brick ceilings were held up by 336 30-foot pillars scavenged from nearby Roman ruins. Amazingly preserved despite centuries of conflict and siege, the cistern was built in 532 by the Byzantine Emperor Justinian I to store fresh water for the palace and nearby buildings. Nicknamed Yearbatan Sarayi, or “The Sunken Palace” in Turkish, it is known in English as the “Basilica Cistern” because of its location on the site of an ancient basilica.  When Justinian undertook the building of the cistern, Constantinople was still in the shadow of the devastating Nika Revolt which took place in January of that year. The Byzantine equivalent of soccer riots gone massively out of control, the revolt took place in the wake of a hotly contested chariot race and culminated in the burning of much of the imperial city, and the killing of 30,000 rioters by Justinian’s troops. The cisterns were built as part of the rebuilding efforts in the aftermath.  In the past, visitors could rent a rowboat to float past the columns in the dripping gloom. Restorations in the late 1980s dredged the silted-in floor and added lighting, elevated walkways, and a cafe for visitors. There are still fish in the now-shallow water, helping to keep the water clear.  The two giant Gorgon-head pillar bases at the far end of the cistern are an intriguing mystery. It is suspected that they may have been pulled out of an older pagan temple, where motifs of the famous Gorgon Medusa were used as a protective emblem. It is possible that the placement of these two faces—upside down and sideways, at the base of pillars—may have been a deliberate display of the power of the new Christian Empire. Or it’s possible that the stones were just the right size. The Atlas Obscura Podcast is a short, daily celebration of all the world’s strange and wondrous places.

"An Underground Wonder A city as ancient as Istanbul has many layers of history, and you’ll have to go below the surface to see the Basilica Cistern, the largest of the underground cisterns. Built in the sixth century for the Byzantine emperor Justinian, the atmospheric reservoir is supported by 336 columns, many of which have been repurposed from other ruins over the centuries. The Medusa-head column bases are a favorite to photograph, along with the carp that swim silently in the dimly lit waters. The cistern is located between the Blue Mosque and Hagia Sophia, and the best time to visit is simply whenever the line looks short, especially on a hot summer day—it’s always cooler underground."

The Basilica Cistern is certainly an atmospheric and unique site to visit, but there are a few things worth knowing before you go. First and foremost, I would strongly recommend buying tickets in advance. On the day we visited, the ticket queue stretched for around two and a half hours, and staff did not manage the line particularly well, which caused confusion and frustration for many visitors; particularly given the complete lack of shade. Inside, the space is undeniably impressive — vast marble columns rising from the water and the famous Medusa head tucked away in a corner create a dramatic and almost otherworldly setting. However, the experience is let down by the lack of information. Guards usher people through quite quickly, so there is not always enough time to stop and read the few plaques available. For this reason, I would recommend paying extra for the audio guide, as without it you gain very little understanding of the history or significance of what you are looking at. Given the price of admission and the scale of the crowds, the overall value feels questionable. The cistern itself is fascinating, but the presentation does not match the potential of the site. Some improvements — such as projecting short films or historical reconstructions onto the walls, or including a basic audio track with the ticket — could make the visit much more engaging and worthwhile. As it stands, it is worth seeing once, but don’t expect a relaxed or informative experience unless you plan ahead.

The Basilica Cistern is a truly unique and atmospheric place to visit in Istanbul. It offers a very different kind of experience — dark, mysterious, and beautifully lit with soft reflections on the water. The ancient columns and lighting create a dramatic setting, and the Medusa head statue at the end adds a mystical touch that leaves a lasting impression. The site is well-maintained, and the staff were courteous and helpful throughout. However, one thing to note — it’s not stroller-friendly. There are stairs to go down and no ramp, so carrying a stroller by hand can be quite difficult, especially if you’re visiting with kids. It would be great if better accessibility options were provided. Other than that, it’s a fascinating and historic spot that I’d definitely recommend if you’re in the Sultanahmet area.

Step into Istanbul’s hidden underground history! The Basilica Cistern is not just visually stunning, but deeply historical. Built during the Byzantine era, it once stored water for the Great Palace—and walking among the ancient columns truly feels like stepping back in time. The Medusa heads are especially fascinating, surrounded by mystery and legend. I visited on a weekday and bought tickets online in advance—it was definitely the right choice. The walk-in line was much longer, but with the online ticket, I entered quickly with minimal waiting. If you’re into history or architecture, this place is unforgettable. A short visit, but rich in atmosphere and historical depth. Don’t miss it!

A beautiful and historic place. We visited on the weekend, and it was very crowded. If you’re a tourist, you don’t need to wait in the extremely long line of locals. I’m not sure if entry is free for them, but tourists need to buy a ticket — just go straight to the counter, get your ticket, and you can enter without standing in that line. The ticket costs 1,500 TL per person. If you want the audio guide, it’s an extra 200 TL, but you must use your own headphones. Unfortunately, since we didn’t have ours, we couldn’t take advantage of the explanations.

A short look around that can be taken at your own pace. I'd read that this can be done in 15mins. Yes it can. You can also look at a famous painting in one minute as well and move on. This is really only interesting if you choose to find it interesting or take your time to appreciate what it is. A huge underground cistern that has survived so many years and even earthquakes over that time. We spent easily over an hour down there and the helpful people setup the audio guide on my phone and I thought it was great. The lighting changed periodically and gave excellent mood to the place, it didn't seem to overcrowded. I would recommend the fast track tickets as the regular line did seem like a long wait in the sun.

The first impression when you walk down the stairs into the basilica – wow. I have to say, it’s the first time in my life I’ve seen something like this. The place is truly unique, with the way the colors of the lights shimmer under the water – amazing. You can see the excellent Roman architecture and sculptures, and there’s a walkway throughout the whole space so you can admire everything. A perfect spot for photography!

A fascinating place that is worth a visit when in Istanbul. The ticket queue was ridiculous and you can easily buy the online tickets on the spot... not sure why everyone was queueing. It's a bit pricey but the place is stunning inside - lights are great and the artwork is cool. I do wish they had more information about the history of the place though, I had to Google the history after leaving the cistern!

I visited the Basilica Cistern in the evening, after 7 PM, and it was truly a memorable experience. The underground atmosphere is impressive – the soft lighting, echoing water, and massive ancient columns create a mysterious and almost cinematic setting. Visiting later in the day meant fewer crowds, which allowed me to really appreciate the details, including the iconic Medusa heads. It’s definitely a place worth seeing for its architectural brilliance and historical significance. The only downside for me was the ticket price – quite steep for the short visit and lack of extra features (like a guide or audio app). Still, a unique and atmospheric site.

The Basilica Cistern is a really old and super unique attraction in Turkey. Built underground in the year 532 as a water filtration system. Ticket required for entry. Upon entry, instant rise in humidity, which makes sense. The entire underground structure is quite astounding. It's a little eerie but also very cool. Lighting is set up so it's easy to navigate. The space itself is actually quite large and you can spend an easy 30-60 min here depending on if you're reading all the informationals. There are also a few pieces or unique art scattered through worth checking out. I would consider it a must see!

We came here on the first night of arriving to Istanbul. Got in line at 8:05 pm and got inside by 8:30pm as the line went fast. Such a novel experience, incredible history and a good stroll in the evening to set the tone for the rest of the trip. There's a corn and chestnut stand outside which we bought from, only 25 lira per corn. I still haven't figured out why it does not have a stench underground even when all the still water is stored down there, I'd think it would smell over time but it doesn't. 1000 lira per person for our admission. Stairs to take to go underground. Fun and a must see!

The Cisterna Basilica, one of and the largest underground cistern is Istanbul. Built between the third and forth Centuries it could hold up to 80,000 cubic metres of water at capacity. It was used for well over a millennia. It is no longer used as a cistern. There are numerous different column styles evideced throught the portion that is accessible to the public. In addition there are two deusa heads carved sideways so as to negate her stare at the base of two. The lights cycle in intensity and color and there are multiple art installations throughout the area/ The walkways are perforated so heels may be a challenge. Also for you photogs out there they were not allowing tripods so I used my iPhone mostly as the DSLR (well me really) with slow shutter and crazy high ISO's THe cistern was a feature in the classic Bond movie "From Russia With Love" and recently "Inferno". The line was crazy but we had hired a guide for the day so were able to skip it and enter immediately.

Definitely worth the visit. Lines are extremely long in the sun to get tickets so suggest you go online to book tickets in advance and use a guide so you can skip the line. Don't wait until the last minute like we did! We got lucky on our last day in town and squeezed this in just an hour or two before we left! This is the most famous underground Roman cistern where city water was collected and it's beautiful. Recently renovated, it has beautiful lights and a light show every hour on the back wall. You'll find sculptures inside and be dripped on from above. I think this was my husbands favorite thing we saw. He's not one for museums and old houses really. A must see if you're here. Don't skip it.

The Basilica Cistern was built in the 6th century and is one of hundreds of ancient water-filtration systems beneath Istanbul. Now kept with only a few meters of water for tourist access guests can visit the historical space and learn about Constantinople's unique history including a former Roman Basilica that stood directly overhead while walking the premises. An architectural marvel considering its age the space was reportedly built by 7000 slaves and continued to supply water to "the First Hill" and Topkapı Palace into modern times. Do yourself a favor and buy tickets online to skip the lines.

The Basilica Cistern is a quick visit and an interesting one. The architecture is beautiful. It's the largest of the cisterns around Istanbul (it's amazing that there were so many of them!). This is a greats to make when you're visiting the Hagia Sophia and the Blue Mosque, as it's just across the plaza from them. It's a site that would take you 15-30 minutes to visit, depending upon how much time you wish to spend here. DO NOT visit if you have any fear of underground spaces, and you might be a little nervous if you have any fears of being buried alive... I think that's highly unlikely since it's been around 15 centuries or so but I know folks who wouldn't visit this if for that reason, so it's a little odd but worth a mention. When I was there the cost was somewhere around $5 USD to get in. This site isn't accessible, since that wasn't really a concern in the time of emperor Justinian. There are several dozen steps to get to the cistern itself. Although there isn't a lot of water inside so that it can be visited by people, it's still wet, which is probably obvious but the point is that it can be slick so be careful. I was worried I'd slip in one area so my awesome, fearless mom ventured over to take some photos of the medusa columns whilst I stayed put. Be careful but definitely take a trip underground.

This is an amazing architectural feat. Built in 532 by Justinian, it supplied water to the residents of the Great Palace and people in Constantinople. Since the water was not purified, unfortunately it may have also led to outbreaks of water borne illnesses. After the conquest of the city by the Ottomans, it remained undiscovered for over a century until people were found to collect water and fish via lowering buckets into their basements. The 336 pillars were recycled from other building projects. Interesting to see the peacock column and the set of Medusa heads. Nice to walk on elevated platforms to the sounds of classical museum mixed with dripping water.

Known in English as the Basilica Cistern, this underground structure was built in the 6th century to catch and store rainwater for the city's residents. This particular one was the largest one out of hundreds and has been turned into a museum. The place has been drained of water with a walkway constructed for tourists to wander inside it. It does not take very long to walk through everything, but we were glad that we visited. It is definitely one of the most unique attractions in Istanbul, and being so close to the Blue Mosque and Hagia Sophia, is definitely worth a look. One of the more interesting sights to keep an eye on is that some of the columns have medusa heads on them.

I did a walking tour while I was in Istanbul. Let's just say that I did a ton of walking that my legs were in the best shape in ages. It was all worth it. The tour was fabulous! One of the stops was at a cistern. It's typically not at the top of anyone's list of tourist attractions. However, stopping at Yerebatan Sarnici was incredible. I love how impressive the underground reservoir was meticulously designed. It is well-lit and detailed. There are lots of columns with a ton of history attached to them, including Medusa as a column. In our tourist group, one person slipped on the stairs. They are narrow and it is kind of dark, so take care going up and down them. I had a great time here. My boyfriend was impressed that my tour had this site as a stop. He had visited this cistern on his own. (97)

Commissioned by the Emperor Justinian in 532 AD, the Yerebatan Sarnici served the water requirements of the Stoa Basilica and surrounding buildings on the first hill in Istanbul for centuries. The cistern is an eerie place. The lighting casts shadows on the Medusa capitals sitting in water, carp swimming about and wooden boardwalks which navigate the tourist through this inner sanctum create the mystery and magical thinking. If you want photos be sure to bring a low light camera. Supported by 336 columns the water coming into this cistern derived from the Black Sea and held an estimated 80,000 cubic meters of water delivered by 20 km of aqueducts. At one time there were 80 cisterns in Istanbul but the Yerebatan Sarnici is the largest and most excavated. Seasonal hours from Nov.-Mid-April are 9-5:30 and Mid-April-Oct. 9-6:30. The cost for an adult is 20 Turkish Lira or $3.45 US. Children under 8 years old are free. A guided tour with skip the line privileges will cost you $9.63 US. The cistern is presently under restoration which makes me feel fortunate that I was able to see it when it was both undisturbed and water filled. Water drips from the ceiling and temperatures are cool with considerable humidity. The Turkish Museum pass can not be used here. The Theodorius Cistern which recently opened is free and is considerably more modern after it's restoration. It is located nearby and both cisterns can be reached by public transportation.

These are the cisterns inside the old city of Istanbul that were used to store water for use by the mosques and residents of the old ciry. They have been featured in many movies including the odd James Bond movie and so on. Go check it out when in town. Sometimes they have night concerts here and I can only imagine it would be divine. If you are claustrophobic you may not like it in here. It is underground and faintly lit.

Its Turkish name describes this place better than its English name of Basilica Cistern. Yerebatan Sarnici is indeed a sunken palace. Step below the ground level, and you will find yourself among the impressive rows of columns supporting the many arches of the ceiling. If you did not step down the descending stairs, you may think you were in an above-ground palace! However, thanks to its subterranean environment, Yerebatan Sarnici still gives an ambiance that no above-ground palace has. Maybe it's the Ottoman music that echoes resoundingly throughout. Maybe it's the mysterious darkness that is dimly lit only by subtle light that reflected from the columns. Maybe it's simply the cold dampness. As you stroll through the columns, take a closer look and you will notice that not all columns are the same. Intended to be permanently flooded as a water storage without any plan of exposing to the public, Yerebatan Sarnici was constructed with various random columns of various styles from different abandoned or destroyed places. This dumpster of forgotten columns ironically formed a beautiful and bizarre collection. For instance, next to ionic columns may be a peculiar column with eyes, and columns too short are supported by misaligned Medusa head bases. This conglomeration of variety further adds to the air of mystery. Unfortunately for me, Yerebatan Sarnici was not as magical as I had envisioned. Books described the fishes that swam among the columns for centuries, but now the columns are standing on dry ground and the fishes have diverted to a pathetic pool. Travel tales spoke of the interesting experience of sipping on coffee below ground level, but instead of a cafe, the only vendor is a tacky cosplay photo booth. Perhaps all these are temporary due to the ongoing restoration, but I was still slightly disappointed by what I saw. Nonetheless, Yerebatan Sarnici is an interesting sight to see, because I believe that this mysterious air in this place can be felt only in person so no photo can do this place justice. The entrance is literally across the street from the must-go Ayasoyfa and the whole palace can be finished within an hour, so unless you are against spending 20 TL cash for admission, I can't see any reason why you would skip this unique experience. Indeed I was somewhat disappointed by the few negative changes, but I still believe that standing among the underground columns is an essential Istanbul experience that should not be missed.

This place is one of my favorite places in Istanbul. The underground cisterns. It's also knows as basilica cisterns. Located right next to Sophia. Very cheap. Only 20 Liras. Absolutely worth seeing if you are around the area. It was absolutely fascinating. Water everywhere, The architecture, the background music, lighting and darkness, the story behind it and the feeling you feel once you are down there..! It was very impressive for sure! I could have stayed over there the entire day just staring at it if I've had time! Must seen attraction!

I think the underground cisterns was my favorite site in Istanbul. It's fairly quick to walk thru and there are no artifacts and what not. I think i liked it because it was built in 6th Century by the Roman empire as a water reservoir. To try to understand how Romans built these huge pillars underground and miles (19 Km) of aqua ducts to bring all this water here boggles my mind. Come to think of it how does it hold water? What made it cool for me was to understand how advanced they actually were in the 4th to 6th century. There are a few things to look for while there, the teardrop pillar and the pair of Medusa heads in the far corner. Im told the Medusa heads were actually from an earlier time period and area and brought here during the time of construction. There are a few myths about medusa; it seems very fitting to be placed here as its dark, damp and i could imagine the real medusa slithering around between the pillars warding off any intruders. It was only 10 TL ($5 US) to get in so i saved a bunch of money by not paying for the additional tour with my tour company, as well as many of the other tours that they offered in Istanbul. It was also very accessible from public transportation (3 TL each way from my hotel)

Such an unexpected site here. This place is underground, so nice to get away from the hot sun. It's not part of the museum pass, so you will have to pay 20 lira for this one. It's some kind of old aqueduct from the Roman empire, the place has a cool vibe to it. I would highly recommend you walk fast all the way to the end to see the "attraction".. basically a big stone of Meduza's head. Once you see that then you can take your time walking back and checking it out. Honestly there isn't much to see, so after about 10-15 min you are ready to get outta there. Worth to visit, but don't plan on being here more than 30 min, it's a quick stop!

The cistern and the aqueduct were places I just had to visit whilst we explored town. It was a hot day, so it was a perfect chance to check out the cistern. Sadly, it is not part of the Museum Pass and it was 20 lira pp. It's a very cool place that is dark and damp. Watch you step here as it is wet and crowded. We made a loop around and explored. Carp swim around lazily in the dimly lit waters. By the time we had seen Medusa's head on the columns in the back I was ready to jet. Claustrophobic squirrel.

Stunningly beautiful! This is one of the lesser visited attractions - however it's right next door to the Sophia. It's cheap to enter and no crowds, compared to the Sophia and Blue Mosque. Despite having no real expectations of the place, the pictures don't really do this place justice - the architecture is beautiful, and the way it is presented with the up-lighting and darkness make it amazing. This is a must-see while in Istanbul. The first thing you notice is the smell of the water and the freshness in the air. Next you see the amazing brick and mortar work in the ceiling as you descend. Finally you are blown away by the vastness and beauty of the vast cistern. You've got to see this place!

They offer a tour guide at an extra charge. I'm very delicate when it comes to accents. If you don't speak Tex-Mex, we don't speak the same language. They also offer a head set guided tour. I just wanted to explore on my own. It's very touristic in the beginning. Sped right past "buy" section, and went straight to the best part. The Largest Cistern that lies beneath Istanbul not Constantinople! They have walkways through out the cistern, unlike Houston's you have to walk around it. I am fascinated by the light, the temperature, and the noises. I ventured here early in the morning to bypass the long lines I had seen on my afternoon walks. It worked, no line. They don't allow tripods, so leave it at home or you will have to walk back to the entrance to pick it up. I was heading in the opposite direction and someone on their break saw me and yelled for me not to forget. A+ They have signs directing you to the pillars with Medusa head bases. It was early, dark, cold, and made it eerie for me. I kept looking about me, and was frightened going all the way to the back all alone. It wasn't so bad when I finally got a glimpse. I'm not stone! It's a mystery where Medusas heads came from. Rumor has it, ancient building from Roman period. Also a mystery, why one is upside down n the other on it's side. Deliberate I am sure, but WHY? There is also a crying column because it's different from all the rest. A memorial for the slaves who died during construction of the Great Basilica. There is still enough water in this water reservoir to keep large gold fish. I threw my coins in, where they now rest with all the other wishes. My wish, it's okay, I can share it already came true: Love and Happiness.

We were very disappointed. Most of it was under construction so you couldn't see even half of it. No water was in it, it was completely dry. Then they charge 20TL for tourist & 10TL for Turks. If they are going to perform construction on most of the attraction there should be a sign and cheaper price! It took 15 minutes to visit and that was reading everything... It was nothing like the photos. I attached the only good view of the whole place. Very beautiful if we could see it! So sad!

The Basilica Cistern would be just another watery cavern if it wasn't for the history of all the columns and the Medusa heads making it cool. You could see lots of fish swimming in the water, and coins thrown by people who wanted to part with their money and make lots of wishes. We went for the photo op near the front for 5 Euros to wear a funky hat and fancy robes, but I didn't like how my picture came out. Not quite the Turkish princess that I envisioned... :P The Medusa heads were just huge carvings covered in greenish lime or mold or whatever it was. I guess I was expecting some ornate carving with wriggling snakes. I must watch too much tv. :O Got some fresh pomegranate juice at the exit, so that was cool. Fun attraction, and pretty cool overall.

Definitely worth a quick stop, it's not worth more than 30 but the history is interesting as is the architecture.

Basically a sewage under heavy construction/ restoration and mostly closed but still charged 20TL. When I was there all the water was basically pumped out and the entire place was under renovations. Would skip it during the restoration period. Not worth the wait and probably only took us 15 mins to walk around. Guess it's probably looks better usually without all the construction going on

Ooo I liked the Basilica Cistern a lot. This is the biggest cistern in Istanbul. It has been featured in a old James Bond movie. It is one of the most visited sites in Istanbul. I honestly loved everything about it. The dim lightening, faint music in the background, water everywhere, big fishes swimming everywhere, and the medusa columns. The price is 20 lira per person and not included in the Istanbul museum pass. If you love historical places, I will highly recommend it. This is a Byzantine cistern which helped support water into the palace and other areas of Istanbul into the modern times. My few recommendations are to wear sturdy or rain boots because the water gets on the pathways and you can slip. Also bring a good quality camera. Phone pictures won't be sufficient because of the lightening. Go in the morning because in the afternoon and later hours it gets busy. In the morning you will have enough room to walk everywhere in the pace you want. Enjoy this sunken treasure.~

Kind of a cool place! Definitely worth a visit. But it'll only take about 20 minutes to see the whole thing. Definitely unique.

Read and learned about this is history class. The Medusa heads are so cool the see. It's all underground and was once filled with water but they've since drained the water. It smells awful. That's the only bad thing. It smells like mold and is very humid. They also have a photoshoot area set up where you can dress like the olden days and have all your pics taken. That was fun and hilarious. Must do that if you're coming here.

The Basilica Cistern should be on every Istanbul visitor's list of places to see. At the front are normal columns (http://www.yelp.com/biz_photos/yerebatan-sarn%C4%B1c%C4%B1-istanbul?select=ujsYW96VJNYgUXN6McyDew#DAkZIZZQh5011nWmNRRy5Q) and people dressed up who you can pay to have your picture taken with (they have costumes for you to put on too http://www.yelp.com/biz_photos/yerebatan-sarn%C4%B1c%C4%B1-istanbul?select=ujsYW96VJNYgUXN6McyDew#ufpns_woqCxb522cbxiGRw) Follow the catwalks back and you come to some fancier columns (http://www.yelp.com/biz_photos/yerebatan-sarn%C4%B1c%C4%B1-istanbul?select=ujsYW96VJNYgUXN6McyDew#YO-xiSwe3Lc9ih0nkxT5KQ) and a pair of Medusa heads, one is upside down (http://www.yelp.com/biz_photos/yerebatan-sarn%C4%B1c%C4%B1-istanbul?select=ujsYW96VJNYgUXN6McyDew#5zICLxqAmqwkQi3Wcb5GUw) and the other is on her side (http://www.yelp.com/biz_photos/yerebatan-sarn%C4%B1c%C4%B1-istanbul?select=ujsYW96VJNYgUXN6McyDew#ljESJwKMxmOfsZ7EpsPvnQ) Hide your cameras.

This is the perfect refuge on a hot July day from the bustle of this beautiful city with a foot in Asia and a foot in Europe. We did not have a problem with lines above and it was not that crowded below. As others have mentioned, the region has reused stone building parts over centuries and a Greek Medusa head capital has been symbolically dissed by being placed as a base for a column supporting the roof. The lighting is perfect, illuminating the walkways and the arches while maintaining enough darkness for your eyes to adapt. The concern I had with the rules on my visit was the prohibition/extra fee for tripods which I like to use for long video takes. There is also music playing sometimes which would benefit from a good handheld recording system if that fits in your travel kit. They have live performances from time to time which I would love to see, check the website. Istanbul has a long past history and a long future history ahead of it. This cistern is truly one of wonders of the world.

Must see! So huge and impressive "building" just under your feet. Be careful: almost all loads are wet. And don't miss a chance to make selfie with Meduza's head.

This was really cool to see. It's an old defunct underground water storage area that used to feed one of the palaces. There are a whole bunch of columns with orange up lighting that makes it feel like you're inside the movie Clash of the Titans, and makes for great photo ops, especially with the shallow pool of water. There are two Medusa pieces which are supports for two of the many columns. According to our guide, the Medusa pieces were not set incorrectly (one is sideways, the other upside down) as it may seem, but were for structural purposes.

This was unexpectedly one of my favorite things to see in Istanbul. They've done an amazing job of lighting the place just right; it makes you feel the antiquity while also feeling like it's being kept up. You get some amazing photographs, as well as the chance to really marvel at ancient engineering. The Medusa heads are fascinating and enigmatic... Why DID they put them wrongside up? It's also a peaceful respite from the busy and probably hot street outside. I love it for not being a quintessential city tourist destination (i.e. a museum or an art gallery or a zoo or even a restaurant or what-have-you)... It's unique and well worth the 10 TL to get in, even if it's not included in the museum pass.

This is a great, unique tourist attraction. This was originally a repository of drinking water built in the 6th century by Byzantine Emperor Justinian I. It's now a slightly eerie place slightly modified by nice mood lighting, and interesting to see. Being underground enclosed in earth and stone, it's also nice respite from the heat.

This place is perfect because 1) it's 10 Lira a person and 2) it's a nice respite from Topkapi Palace or the Ayasofya. The history alone is incredible! It's not obvious it you're not looking for it. While on the main street that leads to the bigger attractions, the Basilica Cistern was almost completely forgotten by tourists when I visited. I did not wait in line and shared the place with maybe 50 others. This meant I could really take in the engineering marvel that the cistern was. The pillars seem to never end while the up-lighting makes it all the more haunting. Do make a point to see the Medusa heads, hidden off in a corner.

The Basilica Cistern is also known as the sunken palace, and is the largest ancient cistern that lies beneath Istanbul. It was built in the 6th Century and and served as a water reservoir/filtration system. It doesn't take very long to visit the cistern, but I think it's worth it. It's hauntingly beautiful - the pillars are huge! Be sure to walk through to the end to see the two Medusa heads. The cistern is not too far from the Hagia Sophia.

The cistern has turned into a tourist destination where you get pushed through the underground tunnel like a school of fish, only to come out somewhat scaley and wet at the end. ...I'm not totally kidding - the ceiling drips continuously in some parts and when you're stuck in a line of people and you can't move the sploshes are heavy and drenching. The heads of medusa are enough to give you scales, or the shivers in my case. You will go, because you are a tourist, and it's worth it, because you won't see anything like it elsewhere.

Returning to Istanbul on a business trip after having been here a few years earlier on vacation, I wanted to catch a few of the lessor tourist attractions (after Topkapi, the Blue Mosque, Hagia Sofia, etc.) One I had heard about that intrigued me was the Cathedral Cistern. And I am so glad I sought it out. It is in the same area as the other major attractions, but on the other side of a busy street. Signs are plentiful and the entrance fee of 20 TL (Cash only) is a bargain. The reviews here all capture the details of the place, the number of columns, the ancient carvings. But it is difficult to grasp the ethereal beauty of the place. Frankly a great deal of credit goes to the superb lighting that the city has installed that highlight the vastness and the wonderful columns without being intrusive. It is a place to wander for 30 minutes (frankly plenty of time) and just drink in the overall feel of the ages past. Oh, and if you are on your own, spring for the audio tour. It is nicely done!

Yerebatan Sarnici in Turkish, the Basilica Cistern is an amazing underground reservoir. It's 143m long and 65m wide, was created as a water supply connecting to the Bosphorous in AD 532, and then forgotten at some point before the Ottoman conquest. It was rediscovered in 1545 when authorities - acting on stories that people with houses in the area could drop buckets into holes in their basement floors and pull up water with fish - dug it up. It's now a museum. Hundreds of columns, water dripping from the ceiling, carved medusa heads: everything combines to make an eerie, ancient-feeling place. It will usually be quite busy, but is definitely worth a look.

The basilica cistern is definitely worth the wait. The medusa was a little creepy but the infrastructure is impressive.

Apart from not being included in the Ministry of Culture and Tourism 3 or 5-day pass and we had to pay 20TL to get in, this place was a gem! Because of a few cracks in some of the columns, this place was closed to the public for hundreds of years until 1987 when they fixed it up. I am super glad they did because it's incredible to see such a place where they kept fresh water under the city that was transported via aqueducts! They also have this very quiet background music that makes it even more intriguing. Definitely walk to the end to see the columns with Medusa's head. Very cool stuff indeed. I love history!

This hidden gem of a cavern housed the water supply for the ancient Roman city of Constantinople for centuries. Its roof is held aloft by marble pillars and arches, and there are walkways and paths so one can stroll at leisure in cool damp darkness. The most icon item in the cistern is the upside down giant marble Medusa head. Make sure to see it. The lighting here is eerie but one still can take pictures without a flash (the flashes will ruin the ambiance of the place very quickly). The cistern in located almost next door to the Topkapi palce.

This is the Basilica Cisterns. I had seen this place on a television show but had nearly forgotten it existed when it was time to finally begin planning our trip to Istanbul. It came up on most of the travel websites, as well as recommendations from friends so we had to go! It's fairly cheap to get in, and it's right near Sultanahmet Square with Hagia Sophia, Blue Mosque and Topkapi Palace all close by. It may not seem like much, and certainly doesn't do well of making itself prominent near all the big landmarks but you should not skip it. It's dark and wet on the inside but immediately when you get down the stairs you'll say, "wow!" The rows of columns are lit up wonderfully and there are fish swimming in the dark waters that surround them with paths winding around the cavern. It's really awe inspiring. There are also some mysterious Medusa heads in the back corner on the bottom of some columns that they direct you too. None of this seems like much, but you'll really love it. Considering it's not as big or as grand as the other places around, I was surprised to say that this turned out to be one of my favorite sites in Istanbul.
