The Jungfrau, at 13,642 feet, is one of the main summits of the Bernese Alps, located between the southern canton of Bern and the northern canton of Valais, halfway between Interlaken and Fiesch. Together with the Eiger and Mönch, the Jungfrau forms a massive wall overlooking the Bernese Oberland and the Swiss Plateau, one of the most distinctive sights of the Swiss Alps. A large complex of tunnels and buildings has been constructed at the Jungfraujoch, mostly into the south side of the Mönch. There is a hotel, two restaurants, an observatory, a research station, a small cinema, a ski school, and the "Ice Palace", a collection of elaborate ice sculptures. Another tunnel leads outside to a flat, snow-covered area, where one can walk around and look down to the Konkordiaplatz and the Aletsch Glacier, as well as the surrounding mountains.
