Calshot Castle

A Quick History 


Calshot is one of the smaller examples of a grand fortification scheme that  defended the coast  from Cornwall to London.  The castles that Henry VIII built marked a change in warfare. They were the first fortifications in England built to house Cannons and resist cannon fire.  
The age of the gun had arrived.
  
The Castle seen from the South The Keep. 
A practical design with a simple task. Bring as many cannons as possible to bear onto the enemy. 
This was not a grand home for a medieval lord but a structure of war. Built to serve and defend against the power of gunpowder.

Henry VIII's Involvement 
Henry VIII had a great interest in fortification and weapon development and is credited for introducing several innovations. This credit may have been given out of politeness but there is no doubt that his active involvement did influence design improvements. His dissolution of the monasteries released the money required for his fortress building. It is believed that some of the building stone for Calshot Castle came from Bulieu and Netley Abbeys. 

Layers of fire 
The design of the castle with a three story gun tower was a means of dealing with the limitations of the cannons. The early Tudor cannons had limited elevation capability so mounting them at different heights was a method of obtaining a greater depth of fire. The concept was influenced by fortifications in Germany.

1642 
Civil war: The guns are disabled by a Parliamentarian gunboat until it agreed to be support their cause. 
1774 
First major alteration to the castle 
1850 
Modernisation plans rejected as military role of castle limited. 
1856 
Admiralty obtained castle and used for coast guard duties. 
 
Saved: The only one of three to survive 
Calshot was one of three Castles built overlooking Southampton water. The Parliamentarians  left the other two at Netley and St Andrews (at Hamble) disabled after the Civil war.The importance of  Calshost's position ensured its survival as a fortification under the new management. 
 
Up and down: Number of Cannon at the Castle 
The number of guns at Calshot, and the state of repair of the building fluctuated as the threat from abroad changed.

Smugglers and Duty men 
The long history of the Coastguard at the spit was not the result of a concern for mariners safety but of law enforcement. Smuggling was a local industry and the castle at Calshot provided a perfect spot for the Revenue men to be based.
Late 19th and20th Centuries 
New uses. 
1894 
Castle passed to War office and used as defence against torpedo craft 
1895 
Work started on new a battery to the south of the castle. 
1907 Castle altered to take new guns 
1913 Royal Naval air station opened on the spit. 
1918 Guns had been removed. 
1940 Guns remounted on roof of castle and searchlights installed. 
1970s New coast guard tower built and castle passed to English Heritage 
 
New threat, New weapons 
The guns installed in 1895 was the response to the development of a new threat. The threat posed by the combination of two new technologies, steam powered warships and the torpedo. The combination of these had resulted in small fast torpedo boats could conduct night raids on ports and shipping. Quick firing guns (QF) and searchlights was the Admiralties answer to this threat and Calshot was in a prime position to mount such weapons. 

Nothing remains 
Not enough room existed within the Castle for the planned QF guns. A new battery was therefore  built the South. The new battery mounted two 4.7 inch guns and four 12 pdr guns. Later hanger builder has destroyed the remains of this  construction but the site of the roof mounted guns (1907) can still be seen. 

Seaplanes, fast Launches and Lawrence of Arabia 
The air station that grew up around the Castle soon acquired a fascinating history of its own. But that is the subject of a web page that will soon be added to this site
