Dunluce Castle is a medieval ruin perched on a cliff edge about 2 miles from Portrush, between the town and Bushmills. It’s reached by a bridge over a steep drop to the Atlantic — genuinely dramatic, and the reason it became Game of Thrones’s Iron Islands stronghold, House Greyjoy’s seat, in seasons 2 and 6.
History
The earliest recorded castle here dates to the 13th century, built by Richard óg de Burgh, 2nd Earl of Ulster. The ruins visible today are mostly 16th century, from the MacQuillan family, who held it until the MacDonnells took over in the 1550s after a series of battles. Sorley Boy MacDonnell made it his base and rebuilt it in Scottish style, reportedly funded partly by salvage from the Girona, a wrecked Spanish Armada galleon — some of the ship’s cannons are still on display in the gatehouse.
The MacDonnells held the castle through conflict with the English and Scottish crowns, and it remained the family’s main residence until around 1690, after the Battle of the Boyne left the clan impoverished. It’s been a state-care monument since 1928, still technically owned by the MacDonnell family, now managed by the Northern Ireland Environment Agency.
Next to the castle are the remains of Dunluce Town, founded in 1608 by Randal MacDonnell, 1st Earl of Antrim — predating the official Plantation of Ulster, and reportedly among the most advanced housing in Europe at the time (indoor toilets, cobbled streets, a planned grid layout). It was destroyed in the 1641 uprising; around 95% of it is still unexcavated.

What to see
- The Gatehouse — built by the MacQuillans, expanded by the MacDonnells with twin drum towers in Scottish Baronial style; look for a carved medieval Scottish galley on one of the stones.
- The Manor House — the main residence, a Jacobean-style building from around 1620.
- The Two Towers — the oldest surviving structures, built by the MacQuillans in Irish style.
- The kitchens — according to legend, part of the kitchen block collapsed into the sea during a storm in 1639 while the MacDonnells were hosting a dinner, killing all but a kitchen boy and prompting the Countess to abandon the castle for good. Archaeologists have since found the kitchen structure largely intact among the ruins, so the story may have grown in the telling — but it’s a good one regardless.
Local legends
Ghost stories here predate the kitchen collapse. A “White Lady” — said to be a MacQuillan maiden who pined away in the northeast tower — is reported on the cliff edge going back to the 1500s; according to legend, one of the MacQuillan family eventually walked down to speak with her, and she was never seen again.
Booking a guided tour
Several day tours from Dublin combine Dunluce Castle with the Giant’s Causeway, the Dark Hedges, and Belfast — a long day (13–14 hours counting the road from Dublin), but it covers the region’s main sights in one trip if you’re not driving yourself.
