What castle in Ireland once occupied by the MacDonnells is accessible by a bridge?
Glenarm Dating back to Norman times, the village is the family seat of the MacDonnells, who once occupied Dunluce Castle on the north coast. The village is now a Conservation Area, and its main street (Altmore Street) leads directly to Glenarm Forest, from which can be seen Glenarm Castle, on the far bank of the little river which runs through the village to the sea. The imposing entrance to Glenarm Castle, the Barbican Gate, is at the heart of the village. The Castle dates from 1750, with early 19th century alterations. Glenarm claims to be the oldest town in Ulster, having been granted a charter in the 12th century. The Barbican Gate to Glenarm Castle was restored by the Irish Landmark Trust, a conservation charity that saves buildings that are at risk of being lost.
