The Lausanne campus or Dorigny university campus (French: campus lausannois or campus de Dorigny) is a large area in Switzerland where the University of Lausanne (UNIL), the École polytechnique fédérale de Lausanne (EPFL) and several other institutions are located. It is in Dorigny, towards the west of Lausanne, on the shores of Lake Léman. The site is about 2.2 kilometres wide and 31,000 people study and work there.
It is served by Lausanne Metro line 1, from four consecutive stations (UNIL-Dorigny, UNIL-Mouline, UNIL-Sorge and EPFL), and possesses a bicycle sharing system.
In 1946, the citizens refuse a project of airport ("aéroport vaudois Lausanne-Écublens") on the site. In 1963, the Canton of Vaud buy the property of Dorigny; at this time, the University of Lausanne is located in more than forty places in Lausanne.
The first building (the Amphipôle) was built in 1969-1970; in 2013, the campus comprises about sixty buildings. The chief architect of the UNIL campus is Guido Cocchi (1928-2010).
The inauguration of the first EPFL buildings of the new campus took place in 1978.
The campus is mainly located on the municipality of Écublens but part of it are on Chavannes-près-Renens and Saint-Sulpice. The campus has its own postal code: 1015 Lausanne.
A new building (Synathlon) will host the Institute of Sport Sciences of the University of Lausanne, the International Academy of Sport Science and Technology, the International University Sports Federation and the International Sport Cluster.
