My TIP

You can visit the Mirror Chapel only during regular concerts or, exceptionally, exhibitions. The Baroque library of Klementinum is one of the most beautiful libraries in the world. It is possible to see it during the tour, but it is not allowed to go inside.

Make sure you can manage the tour which goes up and then down the spiral staircase. The area is not wheelchair accessible.

Tickets must be purchased in advance, they tend to sell out.
