Antiguo Balneario — 'Old Spa' in Spanish — is a historic bicarbonated thermal establishment that preserves the legacy of an earlier era of spa culture in its architecture, atmosphere, and approach to mineral water treatments. Such historical spas, found across Spain and the Pyrenean borderlands, often retain the charm of their original 19th-century or early 20th-century design, when taking the waters was both a medical prescription and a fashionable social ritual. The establishment invites visitors to experience the therapeutic traditions of a distinguished past within a setting of authentic historical character.
Insider tip — This former balneario in the Pyrénées-Atlantiques draws from bicarbonate-rich thermal waters that bubble up at the foot of the Basque Pyrenees. The historic spa tradition here goes back to the 19th century when wealthy clientele from Bayonne and Pau took cure seasons in the area. The bicarbonate composition makes the water particularly soothing for digestive complaints and stress recovery. The Basque vernacular architecture of the surrounding village lends the site an authentic regional character.
