In 875
Charles the Bald gave Tournus to a community of monks who came to the locality with the relics of
Saint Philibert. The monks had fled
Viking raids on
Noirmoutier, and had previously stopped at
Saint-Philbert-de-Grand-Lieu. Noirmoutier was the location of the first recorded
Viking raid on continental Europe, when raiders attacked the monastery in 799. Around 863 the monk
Ermentarius wrote a history of the transfer of the monastery and the relics of Philibert of Jumièges. The abbey was damaged by a Hungarian invasion in 936/937. The abbey was closed in the seventeenth century and St. Philibert became a
collegiate church. Like many other churches in France, it was secularised as a
Temple of Reason during the
French Revolution.
Roman Catholic worship resumed after the
Concordat of 1801 formally ended the period of dechristianisation. ==Architecture==
