Located in Albelda de Iregua, La Rioja, Spain, the Peña de las Bodegas rock-cut complex forms part of a historic group of excavated spaces between Peña Salagona and Peña de las Bodegas. Architect Sergio Rojo takes over the rehabilitation of the space. Over time, the spaces have been used as columbaria, livestock shelters, and eremitic and monastic dwellings, with the latter associated with the nearby Monastery of San Martín. The site is locally known as the Scriptorium, referencing the Codex Vigilanus, or Codex Albeldensis, written in the monastery’s surroundings.

The complex is carved directly into salagón, a clay-rich stone characteristic of the cliffs. Its architecture is shaped by the removal of material rather than the addition of new construction. A large exterior access area overlooks the valley and the natural gateway to the Cameros region, while the interior extends across two levels connected by stairs. Two long ventilation shafts, known locally as zarceras or tuferas, are also characteristic of La Rioja’s excavated winery architecture.

Architect Sergio Rojo’s rehabilitation introduces a small number of new elements while retaining the existing rock-cut structure. An exterior area with benches provides a gathering space, while cleaned stone surfaces make the excavated spaces more legible. Inside, a backlit floating timber floor guides visitors through the complex, and the openings in the western rock face have been redefined to increase natural light.

The intervention uses dry construction systems and avoids concrete and cement to keep the new work reversible and minimize changes to the excavated architecture. Timber and the existing stone form the primary material palette, combining new elements with the material already present in the site.
