Eremitorio de San Pedro

Eremitorio de San Pedro is a Romanesque rock-cut church located in Argés, a small hamlet within the municipality of Valle de Manzanedo, in the province of Burgos, Spain. Locally it is also known as Cueva de los Gitanos (Cave of the Gypsies), and it belongs to a broader group of cave hermitages scattered across the upper Ebro valley.

What is this place?

The hermitage was carved into a sandstone outcrop above the Ebro River, roughly 30 meters above the water. It is made up of two unequal naves ending in curved apses, originally divided by three arches resting on pillars. Both naves were once covered by barrel vaults built with the typical round Romanesque arch — the vaults themselves have not survived, but the rock still shows how they were split into three bays by transverse arches carved directly into the stone.

Historians link the site's origins to wandering hermits who, between the 8th and 10th centuries, settled the valleys of Bricia, Valdivielso and Manzanedo, cutting places of prayer and habitation straight into the rock face. The earliest written reference dates from 1237, when the site appears under the name Faracjes as property of the Monastery of Rioseco. By the 14th century it was recorded in the Becerro de las Behetrías, at which point it belonged to Pedro Fernández de Velasco. Over the centuries the space was used not only for worship and dwelling but also as a burial ground, as shown by the anthropomorphic graves found carved into the floor.

How do you get there?

The only way in is a narrow footpath branching off the road that connects Incinillas with Valle de Manzanedo. The difficult approach and hidden position above the Ebro canyon are part of the reason the site has survived in reasonably good condition, despite being cut into soft sandstone that erodes easily. Sturdy walking shoes are worth packing, since the final stretch runs over uneven rocky ground with open views down into the river valley.

What will you see on site?

Inside, visitors find the space carved directly into the rock: two naves with visible traces of arches and vault bays, the remains of the apses, and graves cut into the floor. Conservation is fairly poor, a result of both the passage of time and the sandstone itself, so a visit feels more like exploring a raw historical site than touring a fully managed attraction. That character is exactly what draws people interested in early medieval settlement and rock-cut architecture, rather than mass tourism.

When should you visit?

Spring and autumn are the best windows, when temperatures around Burgos province are mild and the access path is neither muddy from rain nor baked hard by summer heat. In summer the exposed rocky terrain can get uncomfortably hot, while in winter the approach can turn hazardous due to damp surfaces and occasional ice on the stones.

Frequently Asked Questions

Is Eremitorio de San Pedro open to visitors? Yes, the site can be visited, but there is no developed tourist infrastructure — access is via a narrow path, and the cave interior has no lighting or safety railings.

Where does the name Cueva de los Gitanos come from? The popular name Cave of the Gypsies refers to local folklore about wandering groups who supposedly sheltered in the rock-cut chambers at various points in time, though this tradition is not documented as solidly as the site's recorded ties to the Monastery of Rioseco.

How old is the site? The oldest parts of the hermitage are attributed to the resettlement of the Ebro valleys between the 8th and 10th centuries, while the first written record of the site dates to 1237.

What else is worth seeing nearby? Valle de Manzanedo itself holds several other rock-cut hermitages along with the remains of the Monastery of Rioseco, to which this site once belonged — a natural extension of the visit for anyone interested in the rock-cut architecture of the Las Merindades region.
