The Circuit de Barcelona-Catalunya is a motorsport race track in Montmeló, Barcelona, Catalonia, Spain. With long straights and a variety of corners, the Circuit de Barcelona-Catalunya is seen as an all-rounder circuit. The track has stands with a capacity of 140,700. Until 2013 the track was known only as the Circuit de Catalunya, before a sponsorship deal with Barcelona City Council added Barcelona to the track's title.
The circuit has been the site of some memorable moments. In 1991, Ayrton Senna and Nigel Mansell went down the entire front straight side-by-side while duelling for second place, with Mansell eventually taking the position and ultimately the race itself.
