Origin and history

The church of St.Thuriau, located in Plumergat (Morbihan), is dedicated to St.Turiau, bishop of Dol-de-Bretagne in the 7th century. It is part of a remarkable architectural ensemble with the chapels of Saint-Servais (17th century) and the Trinity (15th-17th centuries), giving it the nickname of "the village with three bell towers". The building, built from the 11th century on an ancient Druid site, underwent major changes, notably in the 14th century with the addition of a bell tower, and in the 17th century for its exterior walls.

The 12th century capitals, decorated with plant and geometric motifs, have been classified as historical monuments since 1925, a protection extended to the entire church in 2015. Inside, the three-vessel Romanesque nave, initially carpented, was later vaulted. The choir houses a polychrome wooden altarpiece surmounted by a Virgin with the Child from the 14th–15th centuries. The successive restorations (1834, 1859, 1939–1948) preserved its hybrid character, mixing Romanesque elements and Gothic additions.

The 14th century bell tower, massive and flanked by foothills, is crowned with a characteristic bulb. The church, shaped as a Latin cross with a flat bedside, illustrates Breton architectural evolution, from Romanesque origins to medieval and modern transformations. Its history also reflects the religious and community importance of Plumergat, marked by the presence of three religious buildings aligned along Donias Street.
