Church of Saint-Thuriau

The church of St Gildas owes its name to a 12th century priory which depends on the Benedictine abbey on the Rhuys peninsula. It was designed on the site of the former priory by the architect Gilles Monsay who combines medieval forms and baroque style. Work began in 1623 but was not completed until 1663. The bell tower of the three-storey square tower, however, was not completed until 1701. It dominates the whole town and will serve as a model for the region.

Built in the 15th century on a place rich in remains from the Neolithic era, Roman and feudal, the chapel Notre Dame de Penmern stands near the Gulf of Morbihan. The Romanesque chapel was enlarged in the eighteenth and 19th century. Its simple architecture highlights its decorative elements, some of which are classified: a blue vault adorned with stars and 2 models of ships.

Vannes Cathedral was built in the Gothic style on the site of an earlier Romanesque cathedral. Construction began in the 15th century and lasted until the 19th century. Only the 13th-century Romanesque bell tower, which was integrated into the new building, is older. The vaults and the choir were built between 1771 and 1774. Finally, the south tower and the west façade date from the mid-19th century.
