Submarine Mine Observation Station and Observation Post

A submarine mine observation station of 1896, with an observation post of c.1910 to the immediate north, historically associated with a Defence Electric Light emplacement (qv.) and Fort Bovisand (qv.)

MATERIALS: both structures are of shuttered concrete. The observation station is built around an earlier limestone building, and has iron fittings and armour plating.

DESCRIPTION: the observation station is a semi-sunken concrete structure consisting of a pair of observation cells, each approached by steps at the rear end. Each contains a slab containing a recess or instrument socket. The roofs are protected by armour plating and the viewing slits have sliding iron shutters.

The observation post is a small rectangular concrete structure with a door at the rear and a broad opening to the front. The concrete roof is partially collapsed at the front.
