Fort Grange
Built as part of the outer defence line for Gosport along with Fort Brockhurst, Fort Elson and Fort Rowner to the North East and Fort Gomer to the South West. In 1914 23 (Siege) Company Royal Garrison Artillery was based at the Fort. It was used to create number 3 and 4 Siege Batteries Royal Garrison Artillery.
The fort is a Grade II Listed Building and is virtually identical with Forts Brockhurst and Rowner.
In 1917, the Fort Grange Aerodrome became the home to Robert Smith-Barry's School of Special Flying.
There are many surviving details and the main structure is intact, however the earthworks have been much reduced and much of the moat is infilled. In 1916 it was armed with a 1-pounder heavy anti aircraft gun on a travelling carriage. The fort was used as a military headquarters from 1910 and was derelict by 1983. In 1984 Fort Grange became the home of HMS Sultan Royal Naval Volunteer Cadet Corps, and continues to fulfil this role today.
