Oporto

This was a temporary street circuit circuit set in Boavista, on the Atlantic coastline at the mouth of the River Douro west of Porto. It hosted a sports car race in the early 1950s before being included in the Formula 1 World Championship on two occasions. Stirling Moss won by five minutes in 1958 and later supported second-placed Mike Hawthorn's case against disqualification, which proved crucial in that year's title battle. Jack Brabham clinched his second world title here in 1960 by leading a Cooper one-two finish. The round-the-houses circuit consisted of a mixture of fast and slow corners, tramlines and cobble stones, and even passed a fish-drying factory at the conclusion of the lap. Safety concerns forced it to close after 1960 but a shortened version hosted a historic racing festival from 2005 and the World Touring Car Championship visited two years later. The Portuguese tourist board ended its support of racing on the streets of Porto in 2015.
