The Portuguese Grand Prix (Grande Prémio de Portugal) is a motorsports event that was first held in 1951, and then intermittently disappearing for many years before being revived again. The latest revival happened in 2020. For most of its existence, it was a Formula One Grand Prix, but in its early years not every edition was like that: the 1964 event was held as a sportscar race, with the 1965 and 1966 editions being held for Formula Three entrants. All the other events have been held as Formula One races, with the event having been a round of the World Championship in 1958–1960, and then for its every running since 1984. read more
