2. The complex was the former Royal Artillery, Coast Artillery School. The School relocated from Shoeburyness, Essex in September 1940 and was occupied until the end of the Second World War when it was abandoned. The complex was designed by the Royal Engineers from combinations of brick, reinforced concrete, earth and local stone. The elements of the site included observation posts, various calibre gun emplacements, command posts, coastal artillery searchlight emplacements, engine rooms and a magazine complex.
