The Prague Astronomical Clock is one of the most famous astronomical clocks in the world. It is part of the southern wall of the Old Town Hall in Prague. It was built in 1410.
The oldest parts of the astronomical clock are the mechanical clockwork and the astronomical dial from 1410. The clockwork was created by two clockmakers, Mikuláš z Kadaň and Jan Šindel, who later became a professor of mathematics and astronomy at Charles University. The Prague astronomical clock was only the third machine of its kind. The first astronomical clock was built in Padua in 1344.
A calendar was added around 1490 and the astronomical clock was decorated with Gothic figures.
Over the centuries, the astronomical clock has stopped working many times and has been repaired many times. In the 17th century, statues were added, and during a major repair in 1865–1866, moving figures of the apostles were added above the astronomical clock itself.
