The 1957 Monaco Grand Prix was a Formula One motor race held on 19 May 1957 at Monaco. It was race 2 of 8 in the 1957 World Championship of Drivers.
Despite a hesitant start, Moss led away on the first lap from Collins, Fangio, and Hawthorn. On lap 4 coming out of the tunnel, there was mayhem. Moss went straight through the chicane, sending debris from the wrecked barrier crashing onto the circuit.[1] Collins crashed through the quayside barriers trying to avoid it.[2] Fangio and Brooks slowed to make their way through the carnage. Brooks' effort was for nought, being hit by Mike Hawthorn's Ferrari, which lost a wheel.[3] Fangio took the lead from Brooks' damaged car and held it to the chequered flag.
On lap 96, with nine laps to go,[4] von Trips lost a certain third place when his engine blew up. Brabham inherited it, but he in turn lost the place when the engine in his Cooper T43-Climax[5] cut out at Casino five laps from the end.[6] He coasted to the harbour and pushed the car home for 6th place.[7]
