Unique astronomical clock.
The Town Hall on the Old Town Square, which was built in 1338, is a Gothic tower with a bay chapel and a unique astronomical clock with incredible 600 years of age. The Astronomical Clock, which is controlled by a mechanical clockwork, shows the movements of the cosmic bodies and displays the signs of the zodiac.
The biggest attraction to visit the Astronomical Clock, however, is the theater with 12 moving apostles and statues, which is available to viewers every hour. The astronomical clock is a real rarity, as it is one of the most preserved astronomical clocks of medieval times and is also the third oldest astronomical clock in the world. Moreover, nowhere else can we find measurements of Babylonian and Old Czech time.
