Zytglogge is a clock tower in the center of Bern, Switzerland. It was built in the 13th century, and has served as a guard tower, womans prison, clock tower, center of urban land and a civic memorial. It has an important cultural role, and is on the UNESCO's World Heritage list. When it was built, it served as a guard tower in Bern's defensive walls, but as the city grew, it suddenly ended in the middle of the town. It was converted to a womans prison, but in the great fire in 1405 it burned and was restored as a clock tower. The repairs of the towers was not finished until 1983. There is a gilded bell strikier and hour bell at the top. It's name, Zytglogge, means "time bell" in german. The tower may have survived fire, but does it stand a chance against the test of time?
