Presillas rock hermitage

Presillas rock hermitage in Alfoz de Bricia is a sandstone church carved directly into the hillside above the small village of Presillas, in Burgos province, right on the edge of Cantabria and close to the canyons of the upper Ebro river. It stands as one of the most complete surviving examples of rock-cut religious architecture in the region.

What is this place?

The hermitage was carved by medieval anchorites who hollowed out a two-level temple from a sandstone outcrop. The most likely dating points to the 10th century, and the design is linked to Asturian art, the architectural style associated with the early medieval kingdoms of northern Iberia, when monks and hermits sought refuge in caves and rock shelters during a turbulent period of the peninsula's history.

What will you see?

The lower level is divided into three naves, each closed off by its own apse. Rock-cut altars and niches for relics are carved directly into the stone, offering a glimpse into the liturgical routine of the small monastic community that once used the space. A staircase hewn straight out of the rock connects this lower level to the upper floor — itself a striking demonstration of the builders' skill, achieved without the tools available to later masons.

The whole site sits within an oak forest, which shelters the hermitage and turns the approach into something of a small expedition: the quiet of the woods contrasts sharply with the austere, deliberate stonework waiting at the end of the path.

How do you get there?

Presillas lies at the heart of Alfoz de Bricia, a municipality made up of several small settlements scattered across Las Merindades, the historic district in northern Burgos province. The best approach is on foot, via trails that pass through the surrounding villages; because stretches run through forest and are only partially marked, it's worth planning the route in advance and not expecting any tourist infrastructure on site. The hermitage's coordinates are 42.8559389, -3.8748528.

When should you visit?

Given the forest surroundings and the rock-cut nature of the site, spring and autumn are the best times to go, when temperatures are mild and approach paths aren't affected by winter rain and mud. In summer the oak canopy provides shade, but bring your own water — there are no services at the site.

Why is it worth visiting?

Rock hermitages of this kind are genuinely rare on a European scale — they combine the austerity of hermit life with a surprisingly elaborate architectural plan. Three naves, apses, altars and a staircase, all carved from a single mass of rock, show just how demanding it was to build a temple without bringing in any external building material. For anyone interested in the early medieval history of the Iberian Peninsula and its religious architecture, this is a rarely visited yet remarkably authentic site.
