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.
