The Zytglogge is Bern's central landmark giving a show on the hour

This clock tower served as Bern's west gate from 1191-1250.  The tower was once used to imprison prostitutes; the astronomical clock was added in 1527-30 and has been giving a show at four minutes before the hour ever since.  The mechanical figures include bears and a crowing rooster.  Visitors can take a guided tour inside to view the clock mechanism.

The tower once served as the city's west gate.
