Castilla Termal Burgo de Osma is a luxury boutique spa hotel occupying the restored 16th-century University of Santa Catalina in the historic town of Burgo de Osma, Soria province in Castilla y León. The spa draws on lightly mineral oligomineral water to offer contemporary wellness treatments within an extraordinary Renaissance architectural setting. The nearby Romanesque cathedral, medieval village streets, and Duero river valley complete an exceptional cultural and thermal itinerary in one of Spain's least-visited but most beautiful inland regions.
