Abbatiale Saint-Philbert-de-Grand-Lieu, Saint-Philbert-de-Grand-Lieu

Saint-Philibert de Saint-Philbert-de-Grand-Lieu Abbey is an abbey founded in the 9th century by Benedictine monks and located in Saint-Philbert-de-Grand-Lieu, France. Only the abbey church and some buildings around it remain.

A Carolingian style building, it housed for a time the body of Saint Philibert, from whom the town took its name. Following the attack of the site by the Normans, the monks fled with the body of the saint and took refuge in Tournus. The community then reformed to found a priory. Used in the 19th century as a covered market, the abbey church was no longer used for worship. Excavations brought to light the sarcophagus of the saint and the building was classified as a historical monument in 1896. The abbey church has been used for worship since 1936. Today it is one of the most important monuments of the Retz region, open to visitors.
