This was a temporary circuit set inland from Oporto Atlantic coastline. It hosted a sports car race in the early 1950s before being included in the Formula 1 World Championship on two occasions. The round-the-houses circuit consisted of a mixture of fast and slow corners, tramlines and cobbles, and even passed a fish-drying factory at the conclusion of the lap. Safety concerns forced it to close in 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 Oporto in 2015.
