Dunree Fort on the west coast of Inishoven, facing across Loch Swilly towards Fanad, Co. Donegal, Rep. of Ireland. The fort dates far back into history; it was much enlarged in the 19th century. Because of its strategic importance guarding the entrance to the deep water harbour of Lough Swilly, control of the fort was retained by Britain after independence was granted to the Irish Republic, and Irish sovereignty was only secured in 1936. Now houses a fine military museum. See website Link (Archive Link )
