The Monza Circuit is a 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. The circuit's biggest event is the Italian Grand Prix. With the exception of the 1980 running when the track was closed while undergoing refurbishment, the race has been hosted there since 1949.
The starting grid of the "1st Cup Fiera di Milano" race held in 1925.
