 The abbey was destroyed in 845 during the Norman invasions, but a new one was built in the 12th century, serving also as a burial place for the cathedral canons.During the Middle Ages, a priory was also built on the alleged site of their death, at Montmille, which became a place of pilgrimage during the Middle Ages.In 1261, the relics of Lucian, Maximian, and Julian were placed in a new reliquary by William of Grès (Guillaume de Grès), bishop of Beauvais.
