Zytturm
Zug
The Zytturm is a prominent 13th-century tower located in the old town center of Zug, Switzerland. Standing approximately 41.5 to 52 meters tall, it was originally built in the 13th century and later heightened between 1478 and 1480. Its current distinctive form, including the watch room, bay windows, and steep hipped roof, dates from 1557. The tower served historically as a fire watchtower and remains a key symbol of the city. On its eastern side, beneath the clock face, is an intricate astronomical clock installed in 1574, which features four hands indicating the day of the week (linked to Germanic deities and astrological signs), lunar phases, zodiac signs marking the months, and the leap year cycle. Above the clock face, a rotating gold and black globe displays the current phase of the moon. Below the clock are the coats of arms of the Old Eight Cantons that formed the Old Swiss Confederacy between 1353 and 1481. The Zytturm underwent a major renovation in 1952 and is recognized as a site of national and regional significance. Its unique combination of medieval architecture and astronomical features makes it a fascinating attraction for visitors interested in history, astronomy, and Swiss heritage.
