Église Saint-Jacques de Perros-Guirec, Medieval church in Perros-Guirec, France.

Église Saint-Jacques de Perros-Guirec is a stone church with an irregular Latin-cross plan and a flat chevet, built of Côte de Granit Rose granite. Its Romanesque nave of six bays has round-arched arcades on unequal supports: plain round piers to the north, piers ringed by engaged colonnettes to the south. A Gothic five-bay nave continues east, and the west tower carries a balustrade, octagonal dome and slender spire.

The church was built at the end of the 11th century and officially designated as a historical monument in 1901. Over time, architectural features like a western portal added in the 14th century and a dome in the 17th century were incorporated.

The south porch is one of only two Romanesque porches in Brittany with a carved tympanum, the other at Notre-Dame de Kernitron in Lanmeur. Its Christ in Majesty lost the lower symbols of the evangelists when the lintel was replaced by a plain block; only the lion and eagle remain. A 12th-century font decorated with naked, bearded atlantes stands in the nave.

The church stands in the town centre of Perros-Guirec, in the Côtes-d'Armor; the west facade with its tower faces the square, and the south porch, one of only two Romanesque porches with a carved tympanum in Brittany, is the usual entrance side. The building is classified as a monument historique, so visits are made outside services. The interior is covered entirely by timber roofing, and the 18th-century choir enclosure still closes off the chancel.

The south porch is one of only two Romanesque porches in Brittany with a carved tympanum, the other at Notre-Dame de Kernitron in Lanmeur. Its Christ in Majesty lost the lower two evangelist symbols when the lintel was replaced by a plain block; only the lion and the eagle remain, badly eroded by weather.
