One of the main castles of Newry at this date was an ancient abbey building which stood at Mill Street corner, in the northwest end of the abbey complex. Its remains were finally demolished in 1965. The other abbey buildings were once used by Bagenal (30-odd years), as pigsties and stables, according to the O'Neill website. These buildings lay neglected when King William passed through the town. For over 100 years they were nothing more than great massive stores or sheds in the background and not considered as part of the town. Isaac Corry demolished some of them in the early 1800s. Those he did not demolish were turned into homesteads or warehouses. Included were the 140 feet of the great church that was constructed in 1142. He demolished its altar and completely dug up the ancient graveyard beside the church, removing ancient bones by the cartload to St Mary's at Chapel Street. While there was deep mourning from the Catholics of the town at these actions, no one complained because of Corry's status. The graveyard is currently a carpark for Lidl and the great church is now a museum: Bagenal Castle.
