Monasterio de Santa María de Obarenes

Monasterio de Santa María de Obarenes is a ruined former Cistercian monastery standing in the municipality of Encío, in the province of Burgos, deep in the Obarenes mountain range.

What's the story behind this place?

Religious communities had already settled in this spot by the year 867, though under different names — San Lázaro, San Mamés, Santos Justo y Pastor, and San Caprasio. The turning point came in 1151, when King Alfonso VII and his wife Riquilda refounded the monastery, giving it the dedication Santa María de Obarenes and the title "Imperial," a mark of the prestige it held at the time.

The following centuries were not kind to the building. A fire in 1781 destroyed nearly the entire complex, sparing only the church, though the community rebuilt swiftly, repairing the damage within four years. The monastery's story finally closed in the 19th century: the death of its last abbot, Manuel Alvarado, in 1835 coincided with Spain's disamortization, the sweeping secularization of church property that sealed the end of monastic life here.

What will you actually see?

Today only ruins remain, but they still convey the scale and ambition of the original complex. The best-preserved section is the monastery church, built in Gothic style with Cistercian touches and dated to the 13th century. Its interior was laid out on a monumental scale — three naves ending in polygonal apses, once covered by ribbed vaults. Despite centuries of exposure and a missing roof over parts of the structure, the spatial layout of the church is still easy to read, and the sheer mass of the stone walls leaves an impression.

Keep in mind that the site is listed among Spain's endangered heritage monuments, meaning there's no polished tourist infrastructure here — this is a destination for visitors drawn to raw, weathered ruins rather than a restored museum piece.

How do you get there?

Monasterio de Santa María de Obarenes sits within the municipality of Encío, right in the heart of the Obarenes mountains in Burgos province. This is classic northern Castile terrain — winding local roads cutting through sparsely populated, hilly country. A car is by far the easiest way in; plan your route through the villages that make up the Encío municipality. Given how remote the area is, it's worth checking road conditions ahead of time, especially during winter months.

When's the best time to visit?

Spring and early autumn are the most rewarding seasons for exploring the ruins and the surrounding trails through the Obarenes mountains, with mild temperatures and lush vegetation. Summer heat can make longer walks across open ground uncomfortable, while winter brings the added challenge of driving mountain roads in poorer conditions.
