There has been a castle at Glenarm since the 13th century, where it resides at the heart of one of Northern Ireland's oldest estates. The present castle was built by Sir Randal MacDonnell, 1st Earl of Antrim, in 1636, and it has remained in the family since its construction. It is currently owned by Randal, Viscount Dunluce, the son of Alexander McDonnell, 9th Earl of Antrim. The McDonnells have been in Glenarm for nearly 600 years and the Estate has been in the family for 400 years.
The Castle's Walled Garden is open to the public between May and September and hosts many events.
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).
