Monastery of San Salvador de Oña

The San Salvador de Oña Monastery is a monastic complex in Oña featuring buildings from Romanesque and Gothic periods arranged in connected structures. The compound includes various buildings that served religious and residential purposes over the centuries.

The monastery was founded in 1011 by Count Sancho García as a spiritual home for his daughter Tigridia, bringing together nuns from Cillaperlata and monks from Loberuela. The site later underwent significant transformations in its purpose and function.

The church interior displays paintings by monk Dom Alonso of Zamora and a Renaissance altar depicting the Immaculate Conception. These artworks reflect the creative tradition that was nurtured here over the centuries.

The site now operates as a psychiatric hospital administered by the Province of Burgos, which limits visitor access to the buildings. Those interested in the architecture can observe the exterior structures from the surrounding area.

The site holds the sepulchres of various northern Spanish nobles, including Count Sancho García and King Sancho III of Pamplona. These burial places make it an important resting ground for early medieval regional rulers.
