Glenarm Village and Castle – Historic Coastal Spot

📍 Glenarm, Antrim

🏛️ Attraction

Last updated: 28 April 2026

Overview

Glenarm sits on the North Channel coast of County Antrim, the southernmost of the nine Glens of Antrim. With a population of just over 500, the village packs a punch of history, horticulture and seaside charm. The centerpiece is Glenarm Castle – the ancestral home of the Earls of Antrim – surrounded by an award‑winning four‑acre walled garden, a woodland walk, a heritage centre, a lively marina and a handful of quirky eateries. Whether you are tracing the footsteps of the MacDonnells, hunting for tulips in May, or sipping tea in the historic Mushroom House, Glenarm offers a compact yet richly layered Irish experience.

History / Background

  • Early roots – The Glenarm area formed part of the early Christian kingdom of Dal Riada from the 5th to 7th centuries.
  • First castle – A 13th‑century stone castle is recorded in a 1270 Inquisition, likely built by the de Galloways and later held by the Bisset family.
  • MacDonnell era – In the early 16th century the MacDonnells seized the estate; John Bisset had made Glenarm his capital.
  • Present structure – Sir Randal MacDonnell, 1st Earl of Antrim, erected the current stone‑faced castle in 1636. Fires in the 18th and 20th centuries left parts in ruin, but the 5th Earl rebuilt the house in 1750 and further Georgian‑era extensions followed in the early 19th century.
  • Barbican Gate – Restored by the Irish Landmark Trust, the dramatic stone portal now welcomes visitors.
  • 19th‑century trials – During the Great Famine the Earl organised soup kitchens for tenants; a cholera epidemic in 1854 left a mass grave near St Patrick’s Church.
  • Public opening – From the 1990s the McDonnells opened large parts of the estate to the public, adding the walled garden, the Antrim McDonnell Heritage Centre and a programme of cultural events.
  • Recent accolades – The walled garden won the 2023 Historic Houses Garden of the Year award.
