They are located in the historic center of Ourense, on Rúa das Burgas / Praza das Burgas, next to the Barbaña River. They are perfectly integrated into the urban environment, near the Cathedral and the Roman Bridge. Explored since Roman times, these waters were the origin of the city (Aquis Auriensis), and the remains include a 1st-century AD pool-sanctuary and votive stones dedicated to an indigenous deity. The water flows at approximately 64–68°C, with a flow rate of about 300 liters per minute. Rich in minerals such as metasilicates, fluoride, lithium, bicarbonate, and sodium, they are recommended for pruritic skin conditions and rheumatism. Recent studies support their beneficial effect on acne after washing with thermal water.
