The Geneva race track was established in the 1930s between the lake and the Nations square following the closure of the nearby Circuit de Meyrin.The circuit hosted some local motorcycling events before holding its first international event, the 1938 Swiss motorcycle Grand Prix. Racing at the track was suspended during World War II and international competition resumed in 1946 when a number of Grand-Prix races on both two and four wheels were held on this track. In total, five major car races and four major motorcycle races happened on this track between 1938 and 1950.
The original length of the track for the 1938 event was stated as. Over the years small changes were made to the track layout until the track was significantly lengthened for the 1950 event by cutting out the hairpin on Avenue de France and replacing it by two long straits on both sides of Route de Lausanne, connected by a 180-degree hairpin.
Key pilots came here to compete, among them Giuseppe Farina, Raymond Sommer, Maurice Trintignant, Juan Manuel Fangio, Prince Bira.
