Lenan Fort - Chimney Stack

Lenan Fort Inishowen

Lenan Fort Inishowen is one of a number of defensive forts built by the British to defend the deep-water anchorages of Lough Swilly. The gun positions, all of which are linked by extensive underground magazines and passages are still in remarkably good condition.

The fort occupies a headland, and is defended by a ditch system with fortifications at the corners. Much of the fort area comprises the former barracks area. The buildings of the barracks have not stood the test of time well and all that remains of them are the redbrick chimney stacks.

An exploration of an abandoned British military base at Lenan Fort, guarding the mouth of Lough Swilly on the Inishowen peninsula, Donegal, Ireland. Lookout posts, abandoned gun emplacements, underground magazine tunnels and other buildings stand in an amazing location surrounded by lough, sea and mountain.
