Summary
Pillbox, probably built in the summer of 1940.
Reasons for Designation
The World War II pillbox on Eastney Beach, Portsmouth, probably built in the summer of 1940 as part of the anti-invasion defences to the south of the city, is designated at Grade II for the following principal reasons:
* Rarity: the pillbox is a rare variant World War II pillbox design probably built by the Royal Marines, few examples of which are known to survive;
* Design and materials: it is unusual for its stone block construction, multiple embrasures and relatively large size;
* Historical interest: as well as being an element of the anti-invasion defences erected in 1940 to protect the foreshore to the south of the city, it forms part of the long history of the fortifications around the Portsmouth dockyards;
* Group value: it groups with the Grade II listed anti-tank blocks which it overlooks and with the scheduled and listed C19 Eastney batteries to the west and C18 Fort Cumberland to the east.
History
The pillbox at Eastney Beach was presumably built in conjunction with the anti-tank concrete cubes which were laid out on the beach in the summer of 1940, as part of the anti-invasion defences of Portsmouth. The pillbox is a non-standard design probably designed and manned by the Royal Marines (the Admiralty being responsible for Portsmouth's anti-invasion defences) and was sited to cover part of the beach between the C18 and C19 coastal defences of Fort Cumberland to the east and the C19 Eastney Fort East to the west. Eastney Fort East had extra defences, including a machine gun post on the shore, added at this time. The pillbox was built within the grounds of the Royal Marine swimming pool, on the site of an earlier beachfront structure shown on the 1933 Ordnance Survey map. It is unusual in being constructed of stone blocks rather than concrete, probably to blend in better with other buildings along the shore. The blast wall which originally protected the entrance was removed at the start of the C21 and the entrance and embrasures were blocked for health and safety reasons.
