Glenarm Castle history


The McDonnell family arrived in Glenarm from Scotland in the 14th century when John Mor MacDonnell married the heiress to the Glens of Antrim, Marjory Bisset. 

The castle was built in its present spot by Randal McDonnell the 1st Earl of Antrim in 1636. Not long after, it was burnt by the Scots and left in ruin for 90 years.

Rebuilding the castle

After their house in Ballymagarry was burnt down in 1750, the McDonnell family decided to rebuild the Glenarm Castle and return to the estate. 

The design of the building was changed over the years from a grand country house to a gothic-style castle. Another fire destroyed part of the main block in 1929 and reconstruction began in the 1930s.

What it’s like today

The only part of the castle that has managed to survive since the 18th century is the old kitchen, which is still in use today.

While the castle and gardens remain the private residence of the family, it is open to visitors throughout the year with a variety of museums and dining experiences having been added to the estate.
