Originally known as the Mourne Hotel, it was taken over and extended by the Great Northern Railway in the 1890s. William J. Watson was a local architect who worked almost exclusively in south Co. Down, operating out of successively – Newry, Warrenpoint, and Rostrevor. Destroyed by a firebomb during the Northern Ireland Troubles.
