The Astronomical Clock of Zug

The castle of Zug still dominates the skyline. The castle is the former residence of the Counts of Lenzburg, Kyburg and Habsburg.

The first foundations of the castle date from the eleventh and twelfth centuries, a so-called motte. The castle was destroyed in 1352 by the Swiss Confederates, but soon afterwards rebuilt and renovated. The historical museum is housed in the castle nowadays.

The main tower of the town is the Zytturm. The construction began around 1300 and was completed with the construction of the astronomical clock in 1574.

The tower shows the exact time (zyt means time), but also the weekdays, months and the position of the moon.
