Another thing Prague is known for is its clock. The Prague astronomical clock (Prague Orloj) is a medieval astronomical clock attached to the Old Town Hall. The clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the oldest clock still in operation. The Astronomical clock show runs every hour sharp from 9 am until 11 pm. I have seen the show several times.

The clock has been repaired several times since it was installed in 1410. It was last renovated in 2018 for a cost of $2.6 million, many years after I saw it. The restoration created controversy because some people claim that the artwork on the dial was altered.
