This vast Byzantine-style basilica resembles St Mark's in Venice, with its Greek cross shape (rare in France) and cupola. It was completed in around 1173. The lovely Romanesque belltower is the only part of the original church that remains. The restorations carried out by Paul Abadie (1812-1884) were particularly invasive... Inside, a monumental Baroque walnut retable celebrates the Dormition and Assumption of the Blessed Virgin.
