Klementinum

The Klementinum (Clementinum) has undergone a rich architectural evolution. Since the Middle Ages, great European astronomers, scientists, philosophers and musicians have studied and worked here, influencing the development of its remarkable array of buildings.

Albert Einstein taught physics here (1911–12), Wolfgang Amadeus Mozart played music, and Tycho Brahe and Johannes Kepler carried out astronomical measurements.

Construction of the Klementinum began in 1556 following the arrival of the Jesuits. From 1578 to 1726, a former Dominican convent was replaced with Baroque churches and college buildings. Famous architects, sculptors and artists were involved in the design and decoration.

MAJOR BUILDINGS in KLEMENTINUM:

-Mirror Chapel (see picture 1) is a unique chapel within the Klementinum complex. Built in 1724, it features extensive frescoes and intricate carvings, and houses two 18th-century organs, one of which was played by W.A. Mozart during his visits to the Klementinum.

-Astronomical Tower: From the 18th century, astronomical and meteorological observations were made from the tower, the latter providing the oldest continuous series of data in Central Europe.

172 steps lead to the top of the tower for breathtaking 360° views over Prague. A lift operates only part of the way, and the steps are steep, so it is not suitable for visitors with walking difficulties.

-Meridian Hall occupies the 2nd floor of the tower. Light streaming into the hall from the window determines high noon. Astronomical instruments on display measure the distances of celestial objects.

-Baroque Library: Built for the Jesuit University and decorated with magnificent ceiling frescoes, the 18th-century library holds over 20,000 historical books and manuscripts. It also houses a unique collection of geographical and astronomical globes.

-St. Clement's Cathedral and St. Salvator Church form part of the outer wall of the Klementinum and feature some of the finest Baroque architecture in Prague.
