Dunseverick Castle
Dunseverick Castle is a small medieval stone castle on a basalt promontory on the County Antrim coast of Northern Ireland, near the Giant's Causeway. Only fragments of the fortress remain today; the site and surrounding earthworks are National Trust property and a scheduled historic monument. The castle was an important early medieval site and later a manorial and military stronghold before destruction in the 17th century.

As it stood in 1600
What Dunseverick Castle looked like in its prime.
Perched on a grassy basalt promontory above the Atlantic, the castle at its prime consisted of a dark grey basalt residential tower and associated stone gate-lodge set amid earthwork ramparts, with ruined masonry running toward the cliff edges. The stonework was rough-hewn local basalt; the tower rose several storeys with small vertical window slits and an intact roofline in 1600, and a compact ward lay between tower and landward approach.
Its story
The story of Dunseverick Castle.
Saint Patrick, the Vikings and the Slige Midluachra
Traces of an Iron Age promontory fort survive at Dunseverick, and the site has long been considered the northern terminus of one of the five great roads of ancient Ireland, the Slige Midluachra, which ran from here to Emain Macha and onward to Tara and the fording point on the Liffey that became Dublin. Saint Patrick is recorded as visiting the site in the 5th century AD, where he baptised a local man, Olcán, who later became a bishop of Ireland. The stone fort on the promontory was attacked by Viking raiders in 870 AD.
Fergus Mor MacEirc and the Coronation Stone
In the later 6th century AD Dunseverick was the seat of Fergus Mor MacEirc, Fergus the Great, King of Dalriada and great-uncle of the High King of Ireland, Muirceartaigh MacEirc. The site is recorded as the point from which the Lia Fáil, the coronation stone, left Ireland in 500 AD: Muirceartaigh loaned the stone to Fergus for his coronation in western Scotland, part of the sea-kingdom Fergus was then extending.
The Earls of Ulster, the O'Cahans and the McDonnells
Dunseverick became a manorial centre of the Earls of Ulster from around 1250 to 1350, then passed to the O'Cahans as a stronghold from 1560, and later to the McDonnells.
General Munro's Destruction and the National Trust, 1642–1962
The castle was captured and destroyed by General Robert Munro in 1642, and by Cromwellian troops during the 1650s; today only the ruins of the gatelodge remain. Local farmer Jack McCurdy gave the castle and the peninsula on which it stands to the National Trust in 1962. A small residential tower had outlasted the seventeenth-century destruction, but in 1978 it too finally fell to the sea below. The castle and its earthworks are now Scheduled Historic Monuments, and the Causeway Cliff Path passes the site on its way between Dunseverick Harbour and the Giant's Causeway.
