Ain-Diab

The Ain-Diab circuit was a Formula One road course built in 1957 on the suburban streets of Casablanca, Morocco.

The 4.734-mile course was built by the Royal Automobile Club of Morocco and given a full blessing from Sultan Mohammed V; it took merely six weeks to construct. The course was used as the venue for the 1958 Moroccan Grand Prix, the final round in the 1958 Formula One season.

There was a horrible accident on the dusty streets of the road course, when the engine on Stuart Lewis-Evans' Vanwall seized; he crashed heavily and was severely burned, dying in hospital six days later.
