This is a must see!!!! The library is the most impressive thing I’ve seen in Prague. The view from the tower equally impressive. All tours are guided so you need to buy tickets in advance. But what’s great is you can arrive 10 mins before your tour and you’re in. One thing to note: there are ~170 stairs but there are lots of breaks so it’s not too tiring. Highly highly recommend.

It is a must see. You take a glimpse at the library. You cannot take a look only from the door, you cannot enter inside due to the fact that there are all originals inside dated back from 16th century. The guide was really good, she explained everything very well, answered questions and was very kind.

An amazing experience and worth the climb up the top. It's good to note that there are more than 140 steps up to the top but the views are quite spectacular - better than any other view in Prague I'd say. Get your tickets in advanced online or line up before 9am!!! Limited tickets for walk-ins.

Very knowledgeable guide and a quick tour through the Klementinum. Wonderful history if you're interested in astronomy. Views from the top are wonderful, 360 views. Be mindful of lots of steps and narrow staircases

Beautiful place, but NOT WORTH THE MONEY!! 🫤 380 Czech koruna per adult 😶 Only if you intend to do professional photography at the rooftop, maybe... you can watch EVERYTHING on YouTube and online (klementinum.pano3d.cz) with much better quality. They DON'T allow you to go INSIDE the actual library!!! Only watch from distance, so NOT worth your money...

Firstly there are steps to be climbed to move one level to the next. The guide is detailed in her explanation. The highlight is of course the library. It is definitely a gem to see though I am not much of a reader but I like to take awesome stuff like this. If you cannot book online, queue up maybe half an hour before it opens. It has tickets capped at 20 per time slot. We managed to go fortunately 😀😀😀😀

A place with such rich history and some very interesting astronomical discoveries. The tour guide (Andrea) was very lovely and funny, it was a pleasure talking & touring the place with her. The baroque library will leave any booklover absolutely speechless, while the astronomical tower is very intriguing even to those not so familiar or interested in astronomy. A must visit in Prague!

I would try to book tickets online ahead of your trip. Really worth seeing! It is a beautiful baroque library (really effectively a museum) it is not long tour (45 min), but well worth it. You also get to do the astronomical tower, which is even better I think than the astrological clock tower, but if you have difficulty with steep steps the astrological clock tower may be better option. DO NOT miss this tour it is big bang for the buck!

Watched and thoroughly enjoyed the Royal Czech Orchestra ensemble, organist and soprano soloist performing Vivaldi, Bach, Mozart, Smetana, Verdi, Pachelbel and Beethoven. The acoustics were great, the seating was 2nd row and great and the performances were awesome. There are other locations and different shows have some substitutions. Grand piano for organ. Ours included Requiem on titular organ. Was fantastic. I'd go again. Probably choose a slightly different variation each time in Prague.

The worst experience I've had during my week in Prague. 1. The employees are incredibly rude. I was trying to walk into the ticket office and was yelled at by an employee, without explanation and despite others being able to enter. Second, I accidentally booked a tour in Czech and was chastised by the tour guide 2. It is nearly impossible to get tickets; they are frequently sold out. And the website gives conflicting information regarding the tours 3. I guess I wouldn't know since I couldn't understand the guide, but the tour was kind of a rip off. You don't get to go in the library and we didn't visit the mirror chapel It's sad that on my last day in Prague I'm being left with this terrible experience. Everyone else has been wonderful

Super over rated. You don't even get to go into the actual Baroque library. Even after they advertise in all the pictures. The lady at the ticket booth was super rude. Closed the booth window and was eating right in front of us for several minutes while we were all waiting to buy tickets. You can only go with a guided tour. Can't go see it on your own.

Wow! I wasn't sure how the quality of performance would be given the dodgy looking ticket selling stations, but wow. I'm so happy that we spent €24 on tickets to see the orchestra and soprano performance of Four Seasons. I was absolutely spellbound by the soloist who just nails every note in this historic former chapel. Pro Tips: - Definitely request the Section A for the best experience near the performers - Go to the restroom before, there isn't an intermission

Klementinum's website (and door...) say guided tours take place every half hour. They don't mention the likelihood of a long wait due to limited tour sizes. I went in early afternoon midweek during the offseason and had a 2-hour wait. I'm not sure if that's the norm or not, but luckily it is set in the center of town so there's plenty to do in the meantime. The tour shows glimpses of the innards but nothing all too detailed. I'd say it's skippable if you're short on time but otherwise could be a nice stop. It takes about 50 minutes from start to finish. As part of the tour, you'll take a look at the Mirror Chapel (not as many mirrors as you'd think), the Baroque Library (needs a good dusting but is really pretty), and the Meridian. There's then the option to walk up to the lookout tower, which provides a nice view of both Old Town Square and Prague Castle. Maybe not the best vantage point in town but central nonetheless. Really nice during a sunset too! Keep in mind the steps to reach the top are very steep and the elevator doesn't go all the way up, so if you have mobility restrictions, it may not be totally worth the price tag to only see the chapel and library. Overall I'm glad I saw the Klementinum and would recommend if you have the time.

The tour is quite short and kind of mind numbing. You visit the Mirror Chapel, the Library, & the tower above. They were all pretty, but really not worth the time. The view was excellent from the tower, but go to the Tower in Old Town Square, way higher elevation and better view. So many better things to visit while in Prague for the time & money.

Did a tour here and thought it was a bit boring... you have to wait an hour or two for the tour and they just take you up/down the stairs. You won't get to go into the actual library, they'll let you stand at one small corner to see it, you're not even allowed to take pictures. The best part is probably seeing the city from the top. Other than that, there's nothing exciting about the tour, I would recommend skipping it and not waste your time here.

We went on the 50 minute guided tour. You can only get a guided tour. Sign said lift not working today, the sign was laminated..... so not the first day the elevator wasn't working. Even if the lift was working it would not get you up in the tower, but it would make it so you wouldn't have the climb four floors using the spiral stairs. You have to climb up three more flights to get to the tower. The view was great, right in the middle of the old town area. The Library part of the tour was not worth it. The staff was ok, the guide was good but it's not worth 300 each person. Just to stand in the doorway of the library and you can't photographs. Not worth it!!!

WOW!! One of the most amazing places I have ever seen. Well worth going to for the history and what they let you see, which is not a whole lot. The place is so amazing that the tour really should have more sights allowed to be seen, they'd make more money and general sales. Think the place, like a lot of Prague, is having money troubles in general. I must give it 5 stars because of the amazing things one does see!

With only a few hours left on our last day in Prague, my friend and I decided to check out this spot for its Baroque library. Tours are 45 min long and are every half hour. An English speaking guide with a thick accent accompanies you. I really liked our guide because she was friendly but with the acoustics and her accent, it was a bit difficult to understand. There are a lot of steps to climb so I would not recommend this place to someone not able bodied. It kind of reminded me of the Anne Frank house tour. For a small fee (and even smaller if you have a student id), you get to see great views of Prague. The library was off limits but you are able to sneak a peek. Its such a historic place and has such a rich history, I would recommend it to visitors. The views are different from the clock tower views and there are less people here since you have to go with a guided tour.

Worth going! Less crowded than other usual tourists spots and one of the best views of Prague

You can only go with a guide. The guide had a strong accent and you had to pay a lot of attention to understand everything. The library was very pretty and the view was stunning.

Not worth it. You actually do not go into the library and are not allowed to take photos. A complete rip off.

Not worth the money. Very limited tour. No actual access to the library - just a view in.
