The Swiss Grand Prix was held on the Circuit Bremgarten street track from 1950 to 1954, with MotoGP also running their Swiss motorcycle Grand Prix from 1949 to 1954. The circuit eventually fell into disrepair after Switzerland banned motorports after the 1955 Le Mans Disaster, but they made an amendment in 2015 to host electric racing, which is how the Swiss ePrix happened in 2019.
