Prague Towers (7) – Astronomical Tower Klementinum


Klementinum astronomical tower from the yard

Not far from our previous tower (Old Town Tower Bridge) you find a large complex called Klementinum. Klementinum, built on area of 2 hectares, is one of the largest building complexes in Europe. It was built like a jesuit college in 1653-1726 and now it is the seat of Natinal Library. A dominant feature of Klementinum is Astronomical Tower, earlier known as Mathematical Tower. The tower was built in 1722, but due to problems it had to be rebuilt, which lasted another 28 years.

In the courtyard of Klementinum there is standing a monument in honor of Josef Stepling (1716-1778), mathematician, physician and astronomer. He had an imperishable merit for the tower reconstruction and in particular for equipping it with astronomial instruments. In 1891-1911 so called Prague midday used to be signalled by cannonade. With help of the unique crexicular solar clock and the time-measuring instruments the man in tower found the actual time and then he walked onto the gallery at 12 o’clock and sent a signal with flag. The cannoneers, prepared on Mariánské walls, fired out.

The tower is 68 meters high and on the top of it stands the statue of Atlas bearing the Earth, with a symbol of God’s eye.

Views to all directions

To visit the tower you have to buy the ticket for all Baroque interiors of Klementinum, but it is worth seeing. The other attractions are beautiful Mirror Chapel with an in-wrought interior with unique built in mirrors that can not be seen anywhere else and the Baroque Library hall with splendid fresco paintings on the ceiling and a few historically rare big globes.
