Tour of some parts of Clementinum and visit to the world's most beautiful libary

Tour in English language

The route takes you to the Astronomical Tower and the extension that connects it to the northern wing of the Clementinum complex. Here you will have a guided tour of the Baroque Library, described as the most beautiful library in the world.

You may view the Baroque Library but not enter it. The next stop on the tour is the Meridian Hall with period astronomical instruments on the 2nd floor of the Astronomical Tower. For three hundred years the giant Atlas carrying a sky full of stars on his shoulders has been looking down from the top of the tower. These have never been missing in the Clementinum - neither in star charts nor in its halls, where even W. A. Mozart himself walked and played music. The highlight of the tour is the ascent to the gallery of the longest continuously measuring meteorological station in the Czech lands.

Highlights of the sightseeing route: 

  • View (but no entry) of the Baroque library hall decorated with beautiful frescoes on the theme of science and art. In the hall there is a collection of foreign language printed theological literature and several large, historically valuable globes. The library's collection includes 27 thousand volumes, mainly from the field of theology.
  • The Meridian Hall located on the 2nd floor of the tower. This unique room was formerly used as a giant camera obscura, where with the help of a taut string high noon was determined. In the walls of the Meridian Hall, there are 2 original astronomical instruments, namely mural quadrants used to measure the position of the stars. 
  • The 68-metre-high Astronomical Tower, which offers a magnificent view of the centre of Prague. The tower houses an exhibition of historical measuring instruments and interesting facts about the history of the tower. Originally, since 1751 the observation tower was used for astronomical observations and it retained this function until 1938. Since 1752 it has also been associated with meteorological measurements, which became regular and systematic from 1775 onwards. For more than eighty years (1842-1928), it was also from here that the announcement of noon was made to the inhabitants of Prague.
