Built between the 14th and 15th centuries, this is one of the mendicant churches of Galicia. It is in the Gothic style. It has a Latin cross floor plan, with a single nave, transept, wooden roof and chevet with three polygonal apses, covered with ribbed vaults. Notable features on the outside are the main façade and the doorway with pointed archivolts. Inside, the tomb of the admiral and poet Payo Gómez Chamiro, from the 13th century, is of particular interest.
