Glenarm Castle is the home of Viscount and Viscountess Dunluce and their family. The present castle has been in the McDonnell family since it was first built in 1636 and has been their primary residence since moving from Dunluce Castle in 1639. 

The McDonnells have been in Glenarm for nearly 600 years and the Estate has been in the family for 400 years. In the house you will see superb examples of Irish furniture as well as portraits of family members from the early 17th Century through to the present day.

The Walled Garden is one of Ireland’s oldest walled gardens. Originally created to supply the Castle with its fruit and vegetables, it is now filled with exciting flowers and specimen plants to interest the keenest garden enthusiast. 

Whilst here, visitors can enjoy beautiful scenery and enchanted walks in our walled garden and Castle trail, excellent locally sourced food in our charming Tea Room and a little bit of retail therapy in our new Castle Shop.

It was the 2nd Earl of Antrim, and his wife, who finally decided to abandon Dunluce Castle. In 1639 as they were waiting for dinner one evening the kitchen, along with kitchen staff, fell into the sea!
