The 55-meter high Bel-Air Tower in Lausanne, designed by Swiss architect Alphonse Laverrière and completed in 1932, is one of the first skyscrapers in Switzerland. The building and its 15-storey tower were planned from the design stage as a mixed-use project. Still today, the Tour Bel-Air accommodates offices, shops, housing, and an auditorium, the Salle Métropole.
Almost invisible from the outside, Tour Bel-Air features a large interior courtyard. This interior courtyard also shows that the building complex is composed of 4 distinct volumes: the tower, two wings and a base on Rue de Genève, in order to compensate for the hilly terrain.
Tour Bel-Air is listed as a Swiss cultural property of national importance since 1992.
