In use until 1936, and in World War II as a command post and searchlight battery.
The central caponier and North -East loopholed wall remain.
The site spent a considerable number of years after the second world war as a holiday camp.
Unconfirmed information from the builders on a visit to the site suggests that some of the historic features will be retained.
These include the main wall and entrance arch to the battery and some of the concrete emplacements.
