Altinaghree Castle

Altinaghree Castle is a 19th-century fortress set on farmland between Dunnamanagh and Ballyneaner, with stone walls and structural remains that hint at its former architecture. The site preserves sections of the original building and its defensive perimeter.

William Ogilby built the castle around 1860 using stone from Dungiven quarries, establishing it as a family residence. The structure remained occupied for roughly three decades before eventually being abandoned.

The castle served as a gathering place where the Ogilby family welcomed and entertained visitors from across the region. Its grand dining room became the heart of these social occasions.

The ruins are situated on private farmland and cannot be accessed by the public. However, they can be viewed and photographed from the B49 road connecting Dunamanagh and Claudy.

James Douglas Ogilby, the castle owner's son, vanished for seven years before marrying a mill worker and emigrating to Australia. This unusual turn in the family story reveals how life moved in directions far from their Northern Irish roots.
