Agaton Fort, Plymouth - Plymouth, City of (UA)

One of the ring of C19 land forts built to defend Plymouth. Overlooks River Tamar. Irregular pentagonal plan, with deep ditch on four sides protected by caponiers and a counterscarp gallery. Internally the officer's quarters, cookhouse and barracks, seven of twenty open gun positions, one Haxo casement, five expense magazines and two of previous six mortar batteries survive. Ceased military use in 1958 but was used as Heavy Goods Vehicle testing centre (partly in a modern building) until 2015. Vacancy is concerning and there are significant problems with dry rot and vegetation management.
