Glenarm Castle

Glenarm Castle stands at the heart of the village of Glenarm, along the Giant's Causeway coast in County Antrim. The ancestral home of the Earls of Antrim since the 17th century, the castle remains an inhabited private residence. What draws visitors is primarily its historic walled garden, one of Northern Ireland's oldest, nestled between stone walls and ancient woodland.

What You'll See

Glenarm Castle's walled garden is the focal point of any visit. Enclosed by tall stone walls, it features structured flower beds, herbaceous borders and vegetable plots. A neo-medieval Gothic tower marks the entrance to the estate and sets the architectural tone. Woodland surrounding the castle offers walks along the Glenarm River.

History and Context

The castle has been the property of the MacDonnell family, Earls of Antrim, since the early 17th century. Its current structure reflects successive modifications, particularly in the 18th and 19th centuries, which gave it its neo-Gothic character. The walled garden dates to the early 18th century, making it one of Northern Ireland's oldest functioning walled gardens.

Highlights of Your Visit

The Walled Garden

Divided into several compartments, the garden blends ornamental plants and vegetable crops. Stone walls create a microclimate suited to diverse species. Vegetation varies with the seasons: spring and summer months offer the most generous blooms.

The Gothic Tower and Castle Façade

The neo-Gothic entrance tower, visible from the village, is the estate's most photographed architectural feature. It exemplifies the 19th-century Romantic taste for reimagined Medieval aesthetics.

Woodland and the Glenarm River

A trail runs alongside the river through the estate's woodland. It's a tranquil space, away from the village, ideal for observing local wildlife and enjoying the glen landscape typical of Antrim.

Photography Tips

Morning light favours photographing the castle façade and Gothic tower, before tree shadows cover the entrance. Inside the walled garden, soft light from slightly overcast days does more justice to the flower beds than bright sunlight. Check for any photography restrictions upon entry.
