Carrickmines Castle
Carrickmines Castle is the site of a medieval Hiberno-Norse and Norman fortified settlement on the frontier between Dublin and Wicklow. The site once comprised a curtain wall with towers, a central keep or hall house, a surrounding village with mills, and substantial rock-cut defences and moat; much of the archaeology now survives only as subsurface remains. Extensive excavation was carried out before a modern motorway was routed through the site.

As it stood in 1402
The shape it held in its prime.
A medieval stone curtain wall encloses several acres and is periodically reinforced by stout towers, with a central stone keep or hall house rising above a clustered settlement of timber and stone buildings and mills. The fortification is defined by a broad ditch or moat cut into bedrock with masonry revetments and a continuous battlemented wall-walk; timber roofs would cap halls and domestic houses. The place sits low on the southern plains, approached across grassy terrain.
Its story
The story of Carrickmines Castle.
Carrickmines Castle was built in the Middle Ages to protect the English-ruled Pale around Dublin, on the frontier between Dublin and Wicklow. In its prime the fortified settlement comprised a curtain wall with towers, a central keep or hall house, a surrounding village with mills, and substantial rock-cut defences and a moat.
The castle belonged to the Walsh family. In 1402, when the O'Byrne clan of Wicklow moved a large mercenary force to the banks of the Dargle at Bray, the direct route to Dublin would have brought them close to the stronghold of Carrickmines — they apparently hesitated, and the delay allowed the Walshes to send an urgent warning to the city. In the Irish Rebellion of 1641 the Catholic Walshes sided with the native Irish and the Confederate attempt to create the first independent Irish parliament.
The mostly subsurface ruins lay in the path of the M50 motorway, completed in 2005; extensive excavation preceded the road, and sections of the medieval walls and defensive structures were preserved within or under its roundabouts. In 2006, amid corruption allegations, the Criminal Assets Bureau obtained a High Court order freezing 107 acres at Carrickmines owned by Jackson Way Properties and preventing their sale.
