Berne the capital city of Switzerland lies in the Swiss plateau within the Canton of Berne, somewhat west of the center of Switzerland and 20 km north of the Bernese Alps. Berne's city center is largely medieval and has been recognised by UNESCO as a Cultural World Heritage Site. Perhaps its most famous sight is the Zytglogge, an elaborate medieval clock tower with moving puppets. Thanks to 6 kilometers of arcades, the old town boasts one of the longest covered shopping promenades in Europe.
