Saint Saviour's Priory, usually just called St Saviour's, was founded as an Augustinian house in the middle of the twelfth century, and it carries some of the finest Romanesque carving anywhere in this valley. Tradition links its foundation to Saint Laurence O'Toole, who was abbot at Glendalough in the years before 1162, though the connection is an attribution rather than settled fact. What is clear is the quality of the stonework: chevrons, spirals, knotwork, human and animal heads, and a roll moulding finished with a dragon's head.
