The Monza Circuit is a historic 5.793 km (3.600 mi) race track near the city of Monza, north of Milan, in Italy. Built in 1922, it was the world's third purpose-built motor racing circuit after Brooklands and Indianapolis and the oldest in mainland Europe. Track modifications have continuously occurred, to improve spectator safety and reduce curve speeds,[6] but it is still criticised by the current drivers for its lack of run-off areas, most notoriously at the chicane that cuts the Variante della Roggia.
