Speculum Alchemiae

Very beautiful place to visit. The personel was amazing, kind and knowledgeable. The visit is guided and lasts half an hour. The tour starts every 30 minutes. Be careful cause it's a cash only place! Overall, it was a beautiful experience!

Absolutely amazing tour! The highlight was definitely our instructor—she was incredibly knowledgeable and passionate, giving us a full and engaging overview of the site’s deep history and its UNESCO significance. One of the coolest parts is a hidden door that she guides you through—super fun and mysterious! A heads-up: they only accept cash, and the entrance is 10 euros per person, so make sure to have cash on hand before you arrive. Totally worth it for the experience!

You can only do guided tours here and you can only pay in Cash. We had to wait for half an hour for the next tour. I really loved it. The guided Tour takes about half an hour in one of the oldest houses in Prague with a really old cellar. The stories and historical facts were great!

This was a really interesting tour. The guide spoke really good English and was very engaging and interesting. Speculum Alchemiae only offers guided tours so check the times for your chosen language. There are some really old artifacts here and it really does feel like you are stepping back in time. Please note that to get down to the underground area access is only via stairs.

Every half hour you can join a guided tour (English) that costs 10 Euros for adults. The guide girl was great, she simply explained this interesting place. Find time if you're in Prague to visit this place, you'll be glad you did later.

This little museum is fun to visit as you get to explore some of the underground tunnels of Prague and learn about the history of this house. While the museum opens at ten, the first English tour does not start until half past ten. There was no ticket queue, so we ended up having to hang around for half an hour. There are no seats in the waiting area. The museum only accepts cash payments. The lady who took us around presented the information well and was happy to answer questions. The tour lasts thirty minutes. There are no toilets or places to eat in the museum. The ticket area has a souvenir shop. There is no disabled access to this building. While there is only a little walking, the floor is uneven, and there are some uneven steps, so people with mobility issues may find it difficult. The underground area is damp, so this may be something to consider if you have asthma or other breathing issues.

Speculum Alchemiae is a fascinating glimpse into Prague’s mysterious past. Tucked away in the heart of the city, its hidden rooms and alchemical roots make for a truly unique experience. The presentation is wonderfully done—full of atmosphere and charm that pulls you right into the world of old magic and mystery. However, the booking system left a sour note. Though tours are said to run every 30 minutes, missing our original 11 AM slot meant we couldn’t join the next one—even though we arrived four minutes early. We waited until noon, only to be packed into a cramped space with a large group, which made the whole experience feel rushed and uncomfortable. I was genuinely excited at first, even thinking about buying one of their curious elixirs to take back to London—but after that, the magic wore off. A place full of potential, but sadly, the execution didn’t live up to the promise.

This is a must see! Where magic and science combine. Tour guide is knowledgeable and engaging. Real alchemist lab uncovered in the 2002 floods.

A short tour but one worth taking if you're into this kind of stuff. I came in somewhat on a whim, just before the start of a new tour. There were four of us, which seemed appropriate for the size of the spaces. Our tour guide was new, but she did a fantastic job nonetheless with giving us cool facts and details about the space. There are lots of cool objects and items. Some authentic, some rebuilt, some just for show. You have to guess which is which before the sand in the hourglass empties or everyone dies. There's even a shop where you can purchase versions of the opium-laden potions of the past. Too bad they're not the same. PS, everyone in our group was wearing all black. It's that kind of place ;)

The Speculum Alchemiae (Museum of Alchemy) was informative and fun. Floods opened up a basement in which alchemical texts and equipment. Recreated with love, this alchemy lab is a blast and the guide was as delightful as one could imagine. My companion, a Prague native, had never heard of the place but found it entertaining, while I nd my other companion found it charming. It's maybe not everyone's cup of tea. but if alchemy (the historical origins of chemistry) appeal, then this is a fantastic couple of hours worth of fun.

WOW! Amazingly great old survivor of hundreds of years of oppression. It was re-discovered recently and bought by a wealthy keeper of antiquities. Well worth the effort to go and learn what real Alchemy hundreds of years ago was about. Very sweet and helpful front desk staff and tour guides. Buy an old style bottle of some of their potions, from the original hundreds of years old recipe! Mine worked.
