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:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
