Zytglogge Bern

Bern’s most famous Old Town sight, this ornate clock tower once formed part of the city’s western gate (1191–1256). Crowds congregate to watch its revolving figures twirl at four minutes before the hour, after which the chimes begin. Tours enter the tower to see the clock mechanism from May to October; contact the tourist office for details. The clock tower supposedly helped Albert Einstein hone his special theory of relativity, developed while working as a patent clerk in Bern.
