The church was constructed under the patronage of Abbot San Genadio in the early 10th century.
The floor plan is rare for the period, featuring two opposing horseshoe-arched apses.
The structure served as the burial place for San Genadio, a significant hermit and bishop in the region.
It is situated at an elevation of over 1,000 meters in the Oza river valley.
The building was part of the Monastery of Santiago de Peñalba, which was abandoned during the Middle Ages.
The horseshoe arches are supported by columns topped with caliphal-style capitals.
Local stone used in construction is slate and quartzite, typical of the surrounding Montes de Aquilano range.
The church interior contains remnants of original fresco paintings depicting geometric and floral motifs.
Iglesia de Santiago de Peñalba is a definitive example of Mozarabic architecture located in the heart of the Valle del Silencio in the Montes de Aquilano. Founded in the 10th century as part of a monastic complex, it is one of the few surviving structures from the Kingdom of León. The church is celebrated for its distinctive horseshoe arches, which reflect both Visigothic and Islamic artistic influences. The building retains its original floor plan, featuring a single nave that ends in two distinct horseshoe-arched apses. Its masonry consists of carefully dressed stone blocks, contributing to its structural preservation over a millennium. The church was declared a National Monument in 1931, cementing its status as a key site of Spanish cultural heritage. It served as a religious center for the hermits who once inhabited the secluded valley. Visitors can observe original mural paintings preserved within the interior walls. The building stands isolated in a village characterized by traditional stone architecture.
The western facade captures the iconic horseshoe doorway against the backdrop of the valley peaks.
