Though other sources of healing 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 spa.
E aínda que outros mananciais de augas minerais curativas son famosos en todo o mundo, é a vila de Spa, a que converteuse en epónimo de calquera lugar que teña unha fonte de auga natural que posúa propiedades especiais para a saúde, como spa.
