Circuit de Monaco, commonly known as the Monaco street circuit, is a renowned temporary street circuit in the Principality of Monaco that hosts the annual Formula 1 Monaco Grand Prix. First used for racing in 1929 and organized by the Automobile Club de Monaco in coordination with Formula 1/FIA, its tight, narrow layout through Monte Carlo and La Condamine—passing landmarks such as Casino Square, the harbour and the Grand Hotel hairpin—makes it one of the most prestigious and technically demanding venues on the international motorsports calendar.
