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 Habsburg army is said to have prepared for its disastrous battle against the Swiss Confederates at Mortgarten in 1315. The first foundations of the castle date from the eleventh and twelfth centuries, a so-called motte. The castle was destroyed in 1352 by Swiss Confederates, but soon afterwards rebuilt and renovated in the style of the time. The historical museum is housed in the castle today. The fifteenth-century city walls and sixteenth-century city towers are also well preserved.

The main tower of the town is the Zytturm. The construction began around 1300 and was completed with the confirmation 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.
