Lenan Head Fort

Lenan Head Fort, Lough Swilly, Inishowen, County Donegal was built in 1895, initially with three 9.2 inch guns. It was refitted in 1911 with two newer 9.2 inch models. An unusual British fortified site, because it was started so late it includes concrete caponiers in an extensive ditch system that climbs the hill to the headland.
