The church forms part of the premises of the monastery of Benedictine nuns, which was founded in the mid-10th century and subsisted as it was until the 19th century (dissolved 1835). The church, which dates from the pre-Romanesque period, preserves part of the 10th century Greek cross and Corinthian capitals. The small bell-tower, called Los Pájaros, is also from the Romanesque period. The Gothic period dates from 1147-1322, with other 16th century additions. The complex was damaged and partly destroyed in 1873 and 1909; what remained was restored in 1945.
