It was constructed in 1990 around the local aerodrome and is 3.020 km (1.877 mi) long. The track runs in an anticlockwise direction. The circuit is owned by the Clube Automóvel do Minho. There is a karting track adjacent to the main track.
The karting circuit was used for the Karting World Championship in 2000 and 2005, while the auto racing circuit is used mostly for Portuguese national motorsports. In October 2009 it hosted its first international motorsports event, the fifth running of the annual European Touring Car Cup.
