Zurich's Old Town has one foot firmly in the past and the other very much at the forefront of Swiss culture. Wandering through the pedestrian-only cobbled streets of the Altstadt (which you can do for hours!), you'll find Switzerland's highest concentration of clubs, as well as theatres, comedy troupes, street performers and young fashion designers selling their wares in small, elegant shops on medieval streets. Landmarks include the Grossmünster’s double towers, built by Charlemagne, and the Peterskirche, which has the distinction of being the church with Europe's largest clockface. Don’t miss Limmatquai, along the Limmat River, one of Zurich's most thronged shopping sites where restaurants and shops are housed in Baroque gilded houses from the 1700s, something like the canalside houses of Amsterdam. It's a great place to actually walk into the past and have the vibrant present all around you!
