Autodromo Nazionale Monza is a motorsport race track near the town of Monza, Italy, north of Milan. It is one of the most historic motor racing circuits in the world.
Construction of the Monza Autodrome was decided in January, 1922, by the Milan Automobile Club to mark the 25th anniversary of the club’s founding in March, 1897, in an embryonic form.
The circuit conceived included a high-speed loop with a total lenght of 4.5 kilometres (2.79 mi) featuring two banked curves on an embankment rising 2.6 metres (8.5 ft) above surrounding terrain.
The first Grand Prix race held at this newly build track was in 1924 and won by Alfa Romeo.
There was major rebuilding in 1938–39, constructing new stands and entrances, resurfacing the track, moving portions of the track and adding two new bends. The resulting layout gave a Grand Prix lap of 6.300 kilometres (3.91 mi), in use until 1954.
In 1954, work began to entirely revamp the circuit because of degration due to lack of attention during World War II.
During this revamp a new high speed oval – Pista di Alta Velocità was also constructed. But after many fatal accidents this oval was never used again for F1 Grand Prix races after 1961.
Pista di Alta Velocità is still there, but in very bad state of repair.
After many updates and track changes the circuit is still used for the Italian F1 Grand Prix.
Other races held at the Monza circuit are the World Championship Superbike, the World Touring Car Championship and the Intereurope Cup for historic cars.
