The center of the Old Town Square is the statue of Jan Hus. The most distinctive ancient building in the square is the self-tweeting bell. Prague's Old Town Square in the evening is very lively. In the cafe on the side of the road, you can have a cup of coffee and sit in the corner of the square and watch the sunset. The unique astronomical clock will have the puppets of Jesus' 12 Apostles in turn to report the time. At the same time, the god of death below will also touch the copper bell. The whole process ended with the cock crow.
