About Kilwaughter Castle

Kilwaughter Castle is a ruined castellated country house near Larne in County Antrim, Northern Ireland. It is a locally notable ruin in the Kilwaughter area.

The site consists of surviving masonry walls, towers and ancillary buildings set within wooded grounds; it is visited mainly for photography and short local walks rather than as a developed visitor attraction. Public access is variable depending on land ownership and local permissions.

The building dates from the 19th century and was constructed as a private country house in a castellated style; it fell into disuse and deterioration during the 20th century and remains a ruin. Repair and redevelopment efforts have been intermittent and the structure is not fully restored.

The ruin sits beside minor roads and forested land a short distance from the town of Larne on the Antrim coast. The surrounding landscape is a mix of woodland and agricultural fields.
