Chapel of the château de Truscat

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.

The church of Saint-Patern was destroyed in the 10th century during the Norman invasions of Brittany and rebuilt in the following century to become an important place of pilgrimage throughout the Middle Ages. The Romanesque church was hit by storms in 1721-1726. The present building was rebuilt in 1727 to the plans of the Vannes architect Olivier Delourme. The grand staircase, the granite tower and its lantern were begun in 1769 but the spire was not completed until 1826.
