a celebrated French Benedictine monastery, belonging to the congregation of St. Maur, situated at the confluence of the Bec and the Rille, nine leagues from Rouen, was founded about 1034, by St. Herluin, its first abbot, near the present site. It became famous as a seat of learning under Lanfranc, then prior, afterwards archbishop, of Canterbury, and was eventually exempted from episcopal jurisdiction, but is now in ruins.
