Circuit de Monaco is a street circuit laid out on the city streets of Monte Carlo and La Condamine around the harbour of the Principality of Monaco. It is commonly, and even officially, referred to as "Monte Carlo" because it is largely inside the Monte Carlo neighbourhood of Monaco. The circuit is annually used on three weekends in April–May for Formula One Monaco Grand Prix, Formula E Monaco ePrix and Historic Grand Prix of Monaco. Formula One's respective feeder series over the years – Formula 3000, GP2 Series and today the Formula 2 championship and Porsche Supercup – also visit the circuit concurrently with Formula One. The Monaco Grand Prix is one of the three events victories in which count towards the Triple Crown of Motorsport. History The idea for a Grand Prix race around the streets of Monaco came from Antony Noghès, the president of the Monegasque motor club, Automobile Club de Monaco, and close friend of the ruling Grimaldi family. The inaugural race was held in 1929 and was won by William Grover-Williams in a Bugatti. To date, only three local drivers have won a race at the circuit. Louis Chiron did it at the non-championship 1931 Monaco Grand Prix; 82 years later, Stefano Coletti crossed the line in first position at the sprint race of the 2013 Monaco GP2 Series round. The third driver to do so was Stéphane Richelmi at the sprint race of the 2014 Monaco GP2 Series round. Evolution of the circuit The track has remained substantially unchanged since its creation in 1929: as a city circuit, its conformation is closely linked to that of the principality's road system. The changes were almost entirely connected to redefinitions of the ordinary roads of the town. In the first editions of the Grand Prix, the start and finish were placed on Boulevard Albert 1er (the innermost straight, which leads to the Sainte Dévote curve). In 1955 the start and finish were moved to the opposite straight, overlooking the promenade (that now houses the pit lane). At the time, neither the Piscine complex nor the "La Rascasse" hairpin existed: after the "Tabac" curve, the route proceeded in the lane that is parallel to today's starting straight: the two sections (separated only by a row of trees) were joined by a single narrow hairpin called the "Gasometer".
