Origin and history
The Abbatial Church of La Trinité-Porhoët, located in the Morbihan department in Brittany, is a Catholic building whose origins date back to at least the twelfth century. It was once the seat of a priory dependent on the abbey of Saint-Jacut, in the former diocese of Saint-Malo. The church has a composite architecture, marked by Romanesque elements (north side, large arcades) and later reconstructions in the thirteenth, fifteenth and eighteenth centuries. Its plan includes a seven-span nave with a low side, a transept and a flat bedside choir.
The 13th-century northern portal combines a broken arch and an arch in the middle of the hangar, illustrating the transition between Romanesque and Gothic. In the 15th century, a dogive vaulted Gothic chapel was added, while the southern arcades and the square of the transept were redone into third points. The choir, the crusillons and the bell tower, rebuilt between 1742 and 1787, completed this stylistic stratification. The frame houses a carved sandstone of angels and instruments of the Passion, and a altarpiece of 1675 decorated with a tree of Jesse carrying the arms of the families of Rohan and Porhoët.
Ranked a historic monument for its portal in 1914, and then registered for the rest of the building in 1975, this place of worship bears witness to the architectural evolution of Brittany. Its interior elevation, with a marked climb towards the choir, and its decorations (flowers, rinceaux) make it a remarkable example of the local religious heritage. The church, owned by the commune, remains a historical and cultural landmark for the Trinity Porhoët and its surroundings.
