The Italian Grand Prix (Gran Premio d'Italia) is one of the longest running events on the Formula One calendar. The Italian Grand Prix was also one of the inaugural Formula One championship races in 1950, and has been held every year since then. The only other championship race for which this is true is the British Grand Prix, and the only other inaugural F1 races that are still on the calendar are the Monaco Grand Prix and the Belgian Grand Prix. Every Formula One Italian Grand Prix since 1950 has been held at Monza except in 1980, when it was held at Imola.
