Astronomical Tower in Clementinum Prague

The Astronomical Tower of Clementinum is a baroque tower with a white facade rising above the complex in Prague's Old Town. It has multiple observation chambers and houses original astronomical instruments from the 18th century.

The tower was built in 1722 as a center for astronomical research, when Prague's scientific work was gaining importance across Europe. Over the centuries, it remained a key place for observing and recording celestial movements.

The tower became a symbol of baroque scientific curiosity, and visitors today can still feel this spirit when walking through its spaces. The blend of religious monastery design and scientific observation shows how faith and the pursuit of knowledge were intertwined during this era.

The tower is accessible via guided tours, which take you up to the observation platform with views across the city. Visitors should expect stairs and can learn about the historical instruments and how they were used.

Since the 18th century, continuous measurement records have been kept at the tower, creating one of Europe's longest weather data series. This record allows scientists today to track climate patterns across many generations.
