The Grand Prix Suisse was once a large international event.
Between 1934 and 1954, motor races took place in Bern that were then known as the "Grandes Epreuves", comparable to today's Formula One. Up to 100,000 spectators thronged around the 7.3km road course. After a serious accident in Le Mans, France, which cost the lives of 81 people, racing around a circuit was banned in Switzerland from 1955. (Pictures: Adriano Cimarosti Collection/RDB/ATP)
