Termas Aquis Querquennis is located near the village of Bande in Ourense Province, Galicia, at a site of extraordinary historical significance — Aquis Querquennis was a Roman legionary encampment established on the Via Nova (Roman road XVIII) in the 1st century CE, where soldiers enjoyed the naturally hot bicarbonate and chloride mineral springs for bathing, making this one of the earliest documented thermal sites on the Iberian Peninsula. The bicarbonate and chloride thermal waters emerge at naturally elevated temperatures from the fractured granite of the Galician massif, following the same geological fault system that connects the renowned Ourense thermal district, and are valued within a long thermal tradition for their warm, multi-mineral character. Today's thermal complex preserves its extraordinary Roman archaeological heritage, where visitors can bathe in waters used by Roman legionaries nearly two thousand years ago while exploring the excavated ruins of the fortress and mansio that made Aquis Querquennis one of Roman Galicia's most important military and civilian rest stops.

Insider tip — The Aquis Querquennis site near the Limia River in Ourense follows the footprint of a Roman military encampment, and the thermal waters here have been channeled for bathing since the first century AD. Bicarbonate and chloride-rich waters emerge at 40°C from granite bedrock, feeding modern pools that sit beside the partially excavated Roman fort. The adjacent As Conchas reservoir creates a striking blue backdrop against the rolling hills of inland Galicia. Archaeology enthusiasts should visit the on-site museum before entering the thermal circuit.
