In the Clementinum are several wonderful concert halls, of the best in all of the Czech Republic.
As visitors, you can mainly walk around the garden areas. Entrance to the building is only allowed during a limited time - from the 20 of May for 4 days only.
If you cut across to th e sidewalk on the other side, you will be able to see the grotesque decorations on the Clementinum.
The Jesuits also built an observatory here, where the pretty towers of the Clementinum are located. The well-known astronomer Johannes Kepler conducted many experiments here that were important and ground breaking.
