Iglesia de Nuestra Señora de Muslera

The Iglesia de Nuestra Señora de Muslera is a medieval church building in Guarnizo with notable architectural features such as a Gothic cross vault with eight ribs and a main altarpiece containing religious figures. Adjacent to the historic church structure is a 17th-century addition that now serves as a hostel for pilgrims.

The church's first documented mention dates to 857, when King Ordoño I donated the building to the Diocese of Oviedo. This early royal donation established a strong connection between the church and regional religious authority.

The church has long served as a gathering place for pilgrims and believers from the surrounding area. Its importance becomes especially clear during religious celebrations, when people come together to maintain traditional practices.

The building is accessible throughout the year, with access normally available during daylight hours. It is helpful to note the proximity of the attached hostel if you plan to spend more time in the area.

Excavations in the 1990s revealed multiple overlapping wall layers in the apse area and several burials containing human remains. These archaeological finds demonstrate that the site contains layers from different periods of its long history of use.
