Glenarm Castle, dating from 1750 with early 19th century alterations lies near the village and the Antrim Estate extends up the Glen for about four miles on both sides of the river. The Church of Ireland stands on the site of a Third Order Franciscan Friary founded about AD 1500 with part of the walls still visible.
Glenarm Castle has been the ancestral seat of the McDonnell family, Earls of Antrim since it was first built by Randal, 1st Earl of Antrim in the 17th century.
In July 2021, the 14th Earl of Antrim, Alexander, sadly passed away. Lord Antrim had an illustrious career as Keeper of Conservation for the Tate Gallery in London. For many years he was the proud custodian of Glenarm Castle.
The current and 15th Earl of Antrim is Randal. Along with his wife Aurora, Lady Antrim and their two children, they currently reside in Glenarm Castle.
