Overview

Glenarm Castle & Garden
Courtesy of Tourism Northern Ireland

Glenarm Castle sits at the heart of the village of Glenarm on the north‑Antrim coast, overlooking the Causeway Coastal Route. The estate remains a private family home – the 15th Earl and Countess of Antrim live on site – but large parts of the grounds are open to the public. Highlights include the 18th‑century walled garden (winner of the 2023 Historic Houses Garden of the Year award), a tranquil woodland walk, the Antrim McDonnell Heritage Centre, and a lively programme of events ranging from Highland games in July to a magical Christmas experience in December.

History

The first fortification on the site dates to the 13th century when John Bisset made Glenarm his capital. The Bisset family held the lands until the early 16th century, when the MacDonnells – later the Earls of Antrim – seized the property. John Mor MacDonnell married the Bisset heiress Marjory in the 14th century, cementing the clan’s presence.

The present stone‑faced castle was erected by Sir Randal MacDonnell, 1st Earl of Antrim, in 1636. A fire set by Scottish forces shortly afterwards left the house a ruin for about 90 years. Rebuilding began after the family’s Ballymagarry house burned in 1750, reshaping the building from a grand country house into a gothic‑style castle. Another serious fire in 1929 damaged the main block; reconstruction continued through the 1930s, giving the interior its current blend of Georgian elegance and gothic touches. The old kitchen is the only room that has survived unchanged since the 18th century.

The walled garden was laid out in the 1820s to supply the household with fresh produce. Over the past two decades Lord and Lady Antrim have restored it to an award‑winning horticultural showcase, complete with heritage fruit trees, water features and seasonal borders.
