Pozo de San Valero

Pozo de San Valero — 'Saint Valero's Well' — is a naturally sulphurous spring or well in Spain whose name honours Saint Valerius of Zaragoza, an early Christian bishop whose association with natural springs reflects the medieval tradition of attributing the qualities of natural waters to saintly intercession. The spring has long been a site of local veneration and bathing use, its sulphurous waters appreciated within the rich tradition of Spanish balneario culture. The well represents the enduring interweaving of religious devotion and mineral water tradition in the Iberian spa landscape.
