Grey Abbey is a ruined Cistercian priory in the village of Greyabbey. It was founded in 1193, by John de Courcy's wife, Affreca (daughter of Godred Olafsson, King of the Isles), as a daughter house of Holmcultram Abbey in Cumbria. It had declined by the late Middle Ages and was dissolved in 1541. It was burnt out by Brian O'Neill in 1572. It was granted to Sir Hugh Montgomery who re-roofed the abbey in 1626 and refurbished it for use as a parish church. It was used until 1778.
The remains consist of a church with cloister and surrounding buildings to the south. Entry is through an elaborate west door, into an aisleless nave, transepts with two chapels in each and a short chancel with tall lancet windows. The buildings around the cloister include an aisled chapter house and a refectory with reader's pulpit, although the west range and cloister walks have disappeared. Three buttresses on the south wall of the nave are part of a conservation programme carried out early in the 20th century. In the north wall of the choir is an effigy tomb which may be that of Affreca, while an armoured knight figure in the north transept may represent John de Courcy. There are also monuments dedicated to the Montgomery family from the 17th and 18th centuries.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
