The Monaco Grand Prix returned in 1955, again as part of the Formula One World Championship, and this would begin a streak of 64 consecutive years in which the race was held. In the 1955 race, Maurice Trintignant won in Monte Carlo for the first time and Chiron again scored points and at 56 became the oldest driver to compete in a Formula One Grand Prix. It was not until 1957, when Fangio won again, that the Grand Prix saw a double winner. Between 1954 and 1961 Fangio's former Mercedes colleague, Stirling Moss, went one better, as did Trintignant, who won the race again in 1958 driving a Cooper. The 1961 race saw Moss fend off three works Ferrari 156s in a year-old privateer Rob Walker Racing Team Lotus 18, to take his third Monaco victory.
