This 12th-century church stands on the Way of St. James, next to the convent of Santo Domingo and close to the river Ega. It is an architectural jewel declared a historical-artistic monument that has been closed for decades. The church has a Romanesque apse and a single nave in three different sections separated by Romanesque pilasters and covered by cross-ribbed vaults. On the outside, the strong buttresses indicate the different interior spaces. The western façade is baroque from the 18th century, in the Mannerist style. The belfry is also from the same period.
