The Zytglogge is a landmark medieval tower in Bern, Switzerland, originally constructed in the early 13th century as a guard tower for the city's western fortifications. Over the centuries, it has served various functions, including a prison, a guard post, and a civic clock tower, anchoring the urban layout of the Old City of Bern.
The structure is best known for its complex astronomical clock, installed in the 15th century. The clock features a mechanical puppet show that activates before each hour, a feature that has made it a central point of interest for centuries. The tower's current appearance reflects significant renovations from the 1770s, which integrated late Baroque elements into the medieval stone core.

Origins as a Gate Tower
1218-1220The Zytglogge was built as the western gate tower of Bern's first city wall. It stood as a defensive structure protecting the entrance to the city until the city expanded and the wall was moved westward.
Installation of the Clock
1405Following a major city fire, the tower was repurposed. The first clock mechanism was installed in 1405, and the astronomical clock face was added shortly thereafter, establishing the tower as the city's primary timekeeper.
Baroque Renovation
1770-1771The tower underwent a major renovation to align with the aesthetic tastes of the 18th century. The exterior was plastered and painted, and the current Rococo-style facade was added, giving the tower its present appearance.
