Dissolution The monastery lands continued to belong to the bishopric until the Revolution of 1688, at which date that see was the richest in the kingdom next to St. Andrews and Glasgow. The priory church, which served also as the cathedral of the diocese, had a long nave without aisles, a choir of about the same length, and a lady chapel beyond. Thomas Sydserf, Bishop of Galloway 1635–8, undertook an ambitious remodelling of the nave. In 1684 the nave and western tower were still intact; but the existing remains consist only of the roofless nave and the extensive vaulted crypts constructed under the eastern end of the church. Such restoration as was possible has been carefully carried out by the third Marquis of Bute. The complex is now a scheduled monument. Excavation The cathedral was subject to a major excavation and restoration in 1886/7 by William Galloway at the expense of John Crichton-Stuart, 3rd Marquess of Bute.
