In today's Spain, there are still medieval monasteries that are not located in large cities or on main tourist routes. They are buildings erected in remote places, on mountains or in areas of difficult access, where nature and silence are part of the religious space itself.
Two of the most representative examples are the Monastery of San Juan de la Peña, in the Aragonese Pyrenees, and the Monastery of San Pedro de Rocas, in the Galician Ribeira Sacra.
Monastery of San Juan de la Peña: built under a rock
The Monastery of San Juan de la Peña originated in the 10th century and developed especially between the 11th and 12th centuries under the patronage of the kings of Aragon.
Its historical importance is enormous, as it became one of the main religious centers of the ancient Aragonese kingdom.
The most striking feature of the complex is its location. The monastery is situated under a large natural rock that protrudes like a gigantic stone visor.
Instead of building upward, the monks took advantage of this natural shelter and built the monastery right underneath.
The rock serves as the building's actual roof. This gives the interior space a very particular feeling: the natural stone is so close that it seems to be a direct part of the architecture.
The church and monastic quarters are built with limestone ashlars. The walls are simple and robust, without large decorative exterior surfaces. The interest lies in the interior, where round arches, columns, and sculpted capitals appear.
These capitals display religious scenes, animals, and symbolic figures. Each one is carved differently, which indicates the intervention of various workshops over time.
Light enters in a limited way, filtering through small openings between the rock and the construction. This creates a dark, cool, and silent atmosphere, very different from that of large urban cathedrals.
Monastery of San Pedro de Rocas: stone as a building
The Monastery of San Pedro de Rocas is one of the oldest monastic complexes in Galicia. Its origins date back to the Early Middle Ages, around the 6th century, although its development as a structured monastery was consolidated between the 9th and 12th centuries.
The most characteristic element of the complex is its direct relationship with the rock. Some of the spaces are excavated into the stone itself, using natural cavities as a base for monastic life.
The main church is simple, with thick stone walls and a very basic structure. It does not seek height or architectural complexity, but rather adaptation to the environment.
Inside, some areas are literally integrated into the rock: columns and walls seem to emerge from the same material as the ground. The space is not completely regularized, as it follows the natural shapes of the terrain.
One of the oldest elements of the complex are the tombs excavated into the stone, which indicate its use as a burial site in addition to being a religious center.
These graves are found directly in the rock, without major ornamentation, which reinforces their primitive and functional character.
The surroundings, surrounded by forest and constant humidity, contribute to the feeling of isolation. The monastery seems to emerge from the landscape rather than having been built upon it.
Two ways of inhabiting stone in the Middle Ages
The Monastery of San Juan de la Peña and the Monastery of San Pedro de Rocas show two very different ways of understanding medieval monastic life.
At San Juan de la Peña, the rock acts as natural protection over a monastery built with architectural technique. At San Pedro de Rocas, the stone itself becomes habitable space, with no clear separation between nature and construction.
Both preserve the same idea: the monastery as a place apart from the world, where architecture does not dominate the landscape, but integrates completely into it.
