Circuit Bremgarten

The Circuit Bremgarten was a 7.28 km (4.524-mi) race course in Bremgarten bei Bern, Switzerland which formerly hosted the Formula One Swiss Grand Prix.

Bremgarten was built as a motorcycle racing track in 1931 in the forests just north of Bern. The circuit itself has no true straight; it is a collection of high-speed corners. It hosted its first automobile race in 1934, which claimed the life of driver Hugh Hamilton. In 1948 it claimed the life of Italian racer Achille Varzi. From the outset, Bremgarten's tree-lined roads, often poor light conditions and changes in road surface made for what was acknowledged to be a very dangerous circuit, especially in the wet.

Bremgarten has not hosted an official motorsport event since 1955, when spectator racing sports, with the exception of hillclimbing and rallying, were banned in Switzerland following the 1955 Le Mans disaster. Although there was a 1982 Swiss Grand Prix, it took place in Dijon, France. On June 6, 2007 an amendment to lift the ban was passed by the lower house of the Swiss parliament, 97 in favour and 77 opposed. The act still has to pass the upper house, which has previously voted down similar proposals.
