The Circuit Calafat was built in 1974 outside the town of the same name in the L'Ametlla de Mar in Catalonia. Private finance paid for the Jordi Xiol designed track, which cost a total of 30 million pesetas. Fans made their own contribution, purchasing shares in the facility worth a total of 25,000 pesetas.
The track closed temporarily during 1982 and 1985 because of legal problems but soon recovered. In 1987 an extension to the circuit was constructed, bringing it up to its current 3.2 km length.
Through 2009-10, a new phase for the modernization and upgrading of the facilities is taking place, with the objective of further development of "Calafat Motor Resort" that complement the existing facilities will be implemented on 55hectares of adjoining land. 2008 saw the re-asphalting of the main circuit, the expansion and improvement of corners and kerbs, refurbished school classroom, pit boxes and fittings for the low grip sliding track. The low grip sliding track is fitted with a sprinkler system and is used for car control and tuition, and measures 770min length. The main straight is 227m long, and the circuit is from 6.5m to 13m wide.
