From the UNESCO Site:
Founded in the 12th century on a hill site surrounded by the Aare River, Berne developed over the centuries in line with a an exceptionally coherent planning concept. The buildings in the Old City, dating from a variety of periods, include 15th-century arcades and 16th-century fountains. Most of the medieval town was restored in the 18th century but it has retained its original character.
The picture above is of the Zytglogge tower of Bern. The Zytglogge tower is a landmark medieval tower in Bern, Switzerland. Built in the early 13th century, it has served the city as guard tower, prison, clock tower, centre of urban life and civic memorial.
We visited Bern last time in January 2012. Living in Switzerland, we are in the city time and again and love its unique old city, the Bundesplatz with the parliament house and Swiss national Bank, as well as the array of restaurants, where you can enjoy sitting outside in the summer and have lunch, coffee and cake etc. The tourist offices have organized a foxtrail of Bern, which will make you learn Bern in a very different way – arts, dialects, histories, tales and customs. I highly recommend a visit to Bern and if you have the time, do the foxtrail. Btw, I take it granted for everyone to know, that Bern is the capital of Switzerland :)!
