Circuit des Nations

The Geneva race track was established in the 1930s between the lake (Geneva) 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 (who had established residency, in Geneva). The closest race tracks were Aix-les-Bains – France (Circuit du Lac) and Lausanne (Circuit du Léman or Blécherette). All were temporary urban race tracks that disappeared shortly after the Le Mans accident in 1955, or before. == 1st Grand Prix des Nations ==

Towards the end of the third Grand Prix des Nations (1950), the engine of Alberto Ascari's Ferrari 340 blew up, pouring oil onto the corner at the end of the Avenue de la Paix. Behind him Luigi Villoresi, in a Ferrari 275, could not avoid the oil, his car skidded, went over the security barrier and ploughed into the crowd. Three spectators were killed; another twenty were injured. Villoresi survived with a severely fractured leg. After this tragedy, stemming like others from the use of street circuits ill-adapted to increasingly high-speed motor racing, the organisers cancelled the following year's event. Geneva would never again host a Grand Prix race. In 1958 motor racing was banned altogether by the Swiss government as an unsafe spectator sport following the death of 80 people at the 1955 24 Hours of Le Mans race. == References ==
