Solent Defences
Created | Updated Mar 12, 2015
An article about Solent Defences. More information and an introduction to follow.
For two thousand years, castles and forts have protected both sides of the Solent - the Isle of Wight and Hampshire. Since the iron age, earth and stone defences have been built for the protection of this part of Britain, and by the turn of the 20th Century the area of the Solent was one of the strongest defended parts of the world, with several forts built to defend the Isle of Wight and the Royal Navy's headquarters at Portsmouth.
Hill Forts
The earliest indications of forts in the Hampshire area are traces of pre-Roman Iron Age hill forts. These are found throughout Hampshire, although the best known are Beacon Hill and Danebury hill fort. Many of these were later adapted into earthwork castles. Sadly there are no written records from the hill forts by their original occupants.

Roman Period
There were defended Roman settlements in Hampshire at Southampton, Silchester and Winchester as well as the Saxon Shore fort of Portchester.1
Mediæval Defences:
During Mediæval times, defence was restricted mainly to castles as well as some defences for vulnerable abbeys. In Hampshire only Winchester and Southampton had town and city walls defending the population as a whole. The Isle of Wight had one castle at Carisbrooke, whereas Hampshire had several Royal castles, castles owned by the Bishop of Winchester as well as castles owned by lesser nobles also.

Device Castles
When King Henry VIII left the Catholic church in 1538, traditional enemies Francis I, King of France and the Emperor Charles V of Spain signed a peace treaty and were encouraged by Pope Paul III to invade England. In response Henry VIII began a national building programme of castles to defend England from invasion. The area around the Isle of Wight and the Solent were of special concern to Henry2. Portsmouth held Britain's first drydock and the Royal Navy base, the Isle of Wight could be used to land a large invading army in preparation for a sustained invasion of the mainland and Southampton was England's third largest port and a rich prize in itself. Southampton's mediæval castle and walls were now outdated and an inadequate defence against ships armed with cannon, and so to defend Southampton from an attacking fleet, coastal castles armed with cannon were ordered to be constructed.
Henry VIII's coastal castles, known as Henrician or Device castles, were the first attempt at constructing a national coastal defence. Most castles were been built in as round, circular structures to help deflect any cannonballs fired at them, for Yarmouth and Sandown Castles on the Isle of Wight a newer, more advanced design was implemented, incorporating arrowhead bastions.
