Aghalurcher (meaning 'Field of the Cast') was a pre-Norman monastery located east of the shore of upper Lough Erne, Northern Ireland, founded according to legend by Saint Ronan in the sixth to early seventh century and dedicated to him in the ninth century. The site includes the ruins of a medieval church with a small gated vault (locked) (where sculptural fragments are stored) and a gateway constructed with stones from the church. The church was remodelled in 1447 with a new roof added. The site seems to have been abandoned after a murder on the altar effectively deconsecrated the church.
The site includes some interesting gravestones of the late eighteenth century, plus an early medieval carved head on the gateway. Additional sculptural fragments from the site are at the Fermanagh County Museum at Enniskillen Castle.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
