Fuensanta began as a spring of water and baths whose use dates back to the Romans, but the first written testimonies are from medieval times. The site has a lot of history, such as the discovery of the Nuevo Manantial in 1868, the installation of electricity in the spa in 1893, the start of the sale of bottled water in Asturian pharmacies in 1913, the launch of food formats in 1983 and the beginning of its international expansion to the United States and Puerto Rico in 1985. In 1968 it began to sell in hospitality and food, already having the fastest water packaging line in Spain. Near the spring there is a route (''Foces del río Banner'') of approximately 10 km. The path is circular: it begins and ends in Fuensanta and passes through Collau de la Canal and Mayao Pastor.
