The 1956 Monaco Grand Prix was a Formula One motor race held on 13 May 1956 at Monaco. It was race 2 of 8 in the 1956 World Championship of Drivers.
The Owen's BRM made their first appearance but after qualifying both cars were withdrawn due to engine valve problems. The other two non-starters were the too-slow Scarlatti and Chiron due to his engine blowing up in practice.
Moss, starting from the middle of the front row, took the lead at Gasworks on the first lap and led every lap. Fangio was not having a good day. He hit the straw bales on lap 2, causing Schell and Musso to retire when trying to avoid him, and on lap 32 he hit the harbour wall, bending a rear wheel. He turned the car over to Castellotti after the pit stop to fix the wheel. On lap 54 while second, Collins came in the pit and turned his car over to Fangio. He resumed in third and passed Behra for second on lap 70, but he was 47 seconds behind Moss. On lap 86 Perdisa's brakes locked when being lapped by Moss, the resulting contact caused Moss's bonnet to lift allowing Fangio to close the gap by two seconds each lap but Moss won with a 6-second cushion.
