"This was super interesting as we got to see hidden tunnels and rooms where alchemy was made. They even show us an original elixir that was found there in the old ages. All the visits are guided and the lady that did our tour was friendly and informative. I did the tour at 14h and we were only four in total which was great! If you are interested in these themes I highly recommend doing this tour."

"Small but very nice museum. The tour is well organised and informative, the rooms have a lot of original details and decorated nicely to express the atmosphere. It gets tight when the tour group is large but everyone gets enough time to explore all the rooms.
Would absolutely recommend."
