Bern is one of the oldest and loveliest cities in Europe, with origins going back to the 12th century. It is on the UNESCO list of World Cultural Heritage. There are many museums, theatres, landmarks, cafés, restaurants and shops - not to mention the weekly market (and the lovely Christmas market) - all of which can be easily reached on foot. The Old Town of Bern has one of the longest "weatherproof" shopping malls in Europe under its six kilometers of covered arcades. The medieval atmosphere, with shops in the cellar vaults is unique. The modern mingles harmoniously with the old in this charming city, as in recent years residents have discreetly added contemporary-style homes and structures to the historic environment.
