Monza (Autodromo Nazionale di Monza)
The "Autodromo Nazionale di Monza" or in short "Monza" is a historic 5.793 km (3.600 mi) racetrack near the city of Monza, north of Milan, in Italy.
It was constructed in 1922 in Monza’s Royal Villa park, and it was the world's third purpose-built motor racing circuit and the oldest in mainland Europe. The circuit has hosted the Italian Grand Prix Formula One race every year but one since the series’ start. Next to F1, the circuit has played host to virtually every form of motorsports over the years: sports prototypes, GTs, touring cars, MotoGP and superbikes. Monza even hosted the legendary Race of Two Worlds in 1957-58, which pitted Indianapolis-style race cars against Formula One cars.
The major features of the main Grand Prix track include the Curva Grande, the Curva di Lesmo, the Variante Ascari and the Curva Alboreto (formerly Curva Parabolica). Even though the Grand Prix circuit has undergone a number of safety-targeted modifications over the years, it still is an extremely fast circuit. As such it is not a coincidence that it is referred to as "The Temple of Speed".
Unfortunately, Monza has been the site of many fatal accidents, especially in the early years of the Formula One world championship and has claimed the lives of 52 drivers and 35 spectators. Track modifications have continuously occurred, to improve spectator safety and reduce curve speeds.
