(SU 48880249) Calshot Castle, an almost intact sixteenth century coastal fort now part of RAF station Calshot, is a single tower surrounded by curtain wall and moat.
The Central Tower, 15.5m in diam & 10.5m high, consists of an octagonal ground floor and basement with two circular upper storeys.
Two shot-lockers (mostly now blocked) are set in each of the eight sides of the ground floor except the western side which is perforated by a large central entrance leading to the basement. This is flanked on one side by a small doorway (giving access to a side staircase to the upper floor), on the other by a shot locker and surmounted by a carved Royal coat-of-arms (fleurs-de-lis quartered first and fourth with the leopards of England) encircled by the Garter. Its large entrance suggests that the basement chamber was the arms store: there is no evidence of any original partitions within the basement.
There are eight gun embrasures on the second floor one above each angle of the ground floor - and various windows, apparently not original, opening from the first. The flat roof has a parapet wall, modern gun platforms and a modern brick built superstructure. On the NNE side of the tower is a complete lead drainpipe, the drain-head bearing the cypher 'ER', a crown and a Tudor rose. Two similar pipes are not decorated.
The 16 sided curtain wall, concentric with the tower, has an external battery. The western part - with a four-centred arched gateway, with portcullis grooves, drawbridge slits and chain holes - is almost as high as the tower, whilst the rest is simply a breastwork with gun embrasures. In the space between curtain wall and tower much modern building has taken place.
Only the northern half of the 8-9m wide, flat-bottomed moat survives. It is now dry and was retained by an internally battered revetment wall, 2.2m high.
The castle, at the end of a pebble spit, is protected on the East by groining, probably contemporary. (7-8)

Calshot Castle located at SZ 488 025. In 1897 the castle gained a new battery, together with a boom defence on whose dolphins (called A and B) were mounted 12-pounder quick-firing (QF) guns. The battery was armed with two 4.7-inch QF guns and four 12-pounder QF guns. The guns were removed in 1906. In 1940 12-pounder guns were mounted on the roof of the castle and a supplementary battery was built opposite these guns (Bungalow Battery- HOB UID 831976). In 1943 Calshot Castle was reduced to care and maintenance. During the Second World War Calshot Castle Battery was manned by 165 Battery of 539 Coast Regiment. (12-13)

Artillery fort built 1539-40 by Henry VIII to defend the entrance to Southampton Water. Before the stone fort was constructed, a temporary earth and wood structure was probably built on the site. The stone castle was a fairly simple design and consisted of a 3 storey central gun tower, a lower concentric curtain wall and a walled moat. The basement floor of the tower is octagonal and the upper 2 storeys round. Guns were mounted in the curtain, upper storey and roof of the tower. The fort was accessed by a drawbridge in the SE and through a 2 storey gatehouse.
A coastal battery was built on the site of the castle in 1902 1902 It was first armed with 2 x 4.7 inch Quick-firing (QF) and 4 x 12 pounder QF guns. In the Second World War it was re-equipped with 2 x 12 pounder QF guns. (14)
Similar in design to Pendennis castle it was built 1539-40. A three-storey keep (15.5m wide by 10.5m high), low concentric curtain wall with a stone-lined moat. 8 embrasures and 18 gun-ports on the keep (roof, first and second floors) and curtain wall. Three additional guns were located on the gatehouse. The gun platforms were clad with lead which had been removed from Beaulieu Abbey. (15)
