Spa is a municipality located in the Belgian province of Liège. It is situated in a romantic valley amid hills which form part of the Ardennes chain, some 35 km (22 miles) southeast of Liège, and 45 km (28 miles) southwest of Aachen
As the famed site of healing hot springs, Spa has been frequented as a watering-place since as early as the 14th century. Though other sources of healing hot mineral springs have become famous throughout the world, it is the town of Spa which has become eponymous with any place having a natural water source that is believed to possess special health-giving properties. As a generic term, the word "spa" may also refer to a resort hotel – usually located near a source of mineral water or hot spring – which offers hot-tub or similar warm-water hydromassage facilities.
The town is perhaps best known today as home to the Circuit de Spa-Francorchamps, which hosts the annual Formula One Belgian Grand Prix. It is also the location of mineral water producer Spa.
