Been here several times, most recently with my brother January 2023. It's quite small but cheap and with a guided tour. Depending on which guide you get, there will be slightly different things covered as there is more history connected to this place than can be covered in just one visit.

en, It was amazing. We recommend. Just be careful so you dont fall there a lot of rocks on the ground. cz, Bylo to hezké. Doporučujeme. Jenom buďte opatrný ať nespadnete je tam hodně kamenů na zemi.

A fascinating tour about alchemy, I would recommend it to anyone who visits Prague. The tours are led by a knowledgeable guide and last about 30 mins. Feedback regarding the positions! Make some tiny ones, maybe less than 100ml so we can take them home in our carry on!

Fantastic little museum that is a thousand times better than the big tourist attractions otherwise in Prague. The service is really good there, they are very friendly compared to other places in Prague where we have experienced unusually bad service! It was really cheap compared to what you get out of the trip. The guided tour was really exciting. You first enter a main room where you get a little story about what they were doing at the time, and then comes the main event. The secret tunnel down to their hidden lab and workplace. It was really fascinating to see and hear about. You get a really good insight into what it was like to be a scientist back in the 6th century and how they had to hide their research from the church while they worked for the king. The guided tour lasts about 30 minutes, (plus questions) All in all a fantastic experience, definitely something you should experience when you are in Prague.

Tours in English were hourly. I went to the store on the day and got a Reservation immediately. The inside of the building is not large, but I was surprised by the various devices. It was interesting to see the idea of alchemy at the time. If you are interested, I don't think you will lose out.

A really exciting visit to a truly re-found alchemistry workshop. One comes on a half-hour guided tour of the workshops as they looked in the Middle Ages. The guide was good at telling details and putting it into a historical context.

Very nice visit to this old museum and a look underground. Guided tour in English , adult 200czk and children/students 150czk. Whether it is all original I don't know but it looks very nice and the guide was very passionate about telling. All in all it takes half an hour

Excellent authentic historical site, not a tourist trap. Very interesting to see and learn about the history here. Bring cash, Czech or Euro. There is a bank nearby with ATMs. The potions are very charming souvenirs, mixed by monks according to ancient recipes, in Czech glass bottles, some hand painted.

Very interesting and something you will not find mentioned in the usual tour books. We heard about it but not until the final few hours in Prague did we end up going. So glad we did not miss it. A very good hour spent. Just not the time of the next English tour if that's what you need.

Fascinating little museum, only accessible with a booked tour. Consisting of a couple of furnished rooms, then a genuinely old underground series of old rooms & passages, it's compact and quite short (30 mins) but very atmospheric. The member of staff taking our tour was very good and informative and the enterance room/shop you start & finish in is beautifully decorated.
