Church of Saint-Patern
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.
