St. Philibert in the center of Tournus. A convent had been here already since the 6th century, dedicated to the martyr St. Valerian. This monastery got raided by the Maurs and in 875 Charles the Bald offered the abbey to a group of monks from Normoutier as their monastery had been destroyed by the Normans.

These monks carried the relics of St. Philibert with them, so for a while the abbey was shared by two communities, each dedicated to their own saint.
