The story of Dungiven Priory
An Augustinian priory was founded at Dungiven around the middle of the 12th century, replacing an earlier church on the same hilltop above the River Roe. It was established under the patronage of the O'Cahan family, the Gaelic lords who ruled this part of what is now County Londonderry, and the church and its lands stayed closely bound to them through the Middle Ages.
The site's treasure is the tomb of Cooey-na-Gall O'Cahan, a chief who died in 1385. His canopied wall-tomb in the chancel carries his armoured effigy above a row of six gallowglasses — kilted Scottish mercenaries — carved in pointed arches. The quality of the carving has led scholars to suggest it was cut by a craftsman from western Scotland, the same world that supplied the O'Cahans with their hired fighting men.
By the late Middle Ages the O'Cahans appear to have built a castle on the site. After the Plantation of Ulster, the place changed hands again: it became the seat of the English planter Sir Edward Doddington, who built a grand house and a defensive bawn here in the early 17th century. That mansion is gone above ground, but archaeological excavations in 1982 uncovered the foundations of the complex, confirming centuries of layered occupation on the one hilltop.
Today the priory survives as a roofless ruin in the care of the Department for Communities' Historic Environment division. The walls of the church and chancel still stand, the O'Cahan tomb is preserved behind a protective grille, and the approach across the river and under the modern road keeps the site feeling set apart from the busy town.
