Overview
Northburgh Castle (locally called Greencastle) dominates the entrance to Lough Foyle on the Inishowen Peninsula. The ruin sits on a narrow rock platform that rises about 45 ft above sea level, giving the fortress a natural defensive edge. Visitors can approach the site from the village of Greencastle or from a scenic shore‑path that runs along the water’s edge, where the castle’s silhouette frames the view toward Magilligan Strand.
History
The castle was erected between 1301 and 1305 by Richard Óg de Burgh, 2nd Earl of Ulster – the so‑called “Red Earl”. His close ties to Edward I of England are evident in the design: the gatehouse with twin polygonal towers mirrors the great Edwardian castles of Caernarfon and Harlech, while the massive curtain wall and polygonal tower echo Welsh military architecture.
After its completion the fortress served three purposes: a symbol of Norman power, an administrative centre, and a launch‑pad for further expansion into the north‑west of Ulster. Its strategic position allowed the Earl to control the vital waterway of Lough Foyle and to keep the O’Neill and O’Donnell clans in check.
The castle’s turbulent saga includes:
- 1316‑1318 – Edward Bruce’s capture – The Scottish king’s brother seized the stronghold, holding it for two years before the Normans recaptured it.
- 1332 – The starvation of Walter Liath de Burgh – Imprisoned in the castle’s dungeon, Walter died of starvation; the event is commemorated in Derry’s coat of arms.
- Mid‑14th century – O’Doherty ownership – After the de Burgh line collapsed, the O’Doherty family made the castle their stronghold.
- 1555 – Cannon fire by the O’Donnells – A heavy bombardment caused extensive damage, and the structure never fully recovered.
- 17th century – Abandonment – A small garrison lingered until the early 1600s; thereafter the ruin fell into decay.
Archaeological work in 1996 uncovered a wide medieval ditch, cobbled approaches, and locally made pottery, confirming the castle’s role as a bustling administrative hub. Today the site is managed by the Office of Public Works and is the focus of a community‑led conservation effort launched in 2021.
What to See & Do
- Twin‑tower gatehouse – The most intact feature, showing the transition from pure fortification to a statement of lordly prestige. Its lower level opens onto a small courtyard, while the upper floor once housed accommodation for the garrison.
- Polygonal tower (Bar Mór) – The larger tower on the northeast corner still rises several storeys, its walls over 12 ft thick. From its base you can imagine the great hall that once stretched along the north curtain wall.
- The dungeon – Visible beneath the main courtyard, this narrow cell is where Walter de Burgh was held. A chain attachment on a central pillar is still discernible.
- Views of Lough Foyle – Walk the shore path to capture the castle framed against the water, especially striking at sunset.
- Nearby medieval church (Temple Moyle) – A short walk (≈400 m) leads to the ruins of a small Norman church, linked to the castle by a local tradition of an underground passage.
- Photography and wildlife – The rocky outcrop attracts seabirds, and the surrounding cliffs provide dramatic backdrops for photographers.
