Spitbank Fort or Spitsand Fort or Spit Sand Fort or simply Spit Fort is a sea fort built as a result of the 1859 Royal Commission. The fort is one of four located in the Solent, near Portsmouth, England, and is now a luxury hotel.
Work on constructing the fort started in 1861 but was soon halted for a review into the best way to defend the Solent and approaches to Portsmouth Harbour. Work restarted in 1867 and was completed in 1878.
Spitbank is smaller than the two main Solent forts, Horse Sand Fort and No Man's Land Fort. Its main purpose was as a further line of defence for ships that made it past the two main forts. It is in diameter across at its base, with one floor and a basement and armour plating only on the seaward side. It was originally planned to have been armed with nine 10" 18-ton rifled muzzle loader (RML) guns on the seaward side, and six 7" seven-ton RML guns on the landward side. However, by the time of completion the plan had changed so that the seaward side received nine 12.5-inch muzzle-loading (RML) guns. From 1884 more modern 12-inch breechloading guns were installed and these were in service until after World War I.〔Hogg, I.V. and Thurston, L.F. (1972). British Artillery Weapons & Ammunition 1914-1918, pages 188-189. Ian Allan, London. ISBN 978-0-7110-0381-1〕
In 1898 the role of the fort was changed to defend against light craft and the roof was fitted out with two 4.7" guns and searchlights. In the early 1900s all but three original large guns were removed. Minor upgrades to the smaller guns and searchlights continued through the years.
The fort was declared surplus to requirements in 1962 and disposed of by the Ministry of Defence in 1982. The fort is now privately owned and operated by AmaZing Venues under the Solent Forts brand. It has 50 rooms, its own dance hall, restaurant, and was once available for private functions with limited accommodation available. It was the venue for the Coalition Festival in the summer of 2009, and other psytrance〔(The Coalition Festival ), 25 July 2009.〕 and hard dance〔(Overload ), HarderFaster.〕 parties.
In 2009 it was put on sale for 〔("£800k fort for sale ... lovely sea views" ), ''The Sun'', 12 October 2009, accessed 12 October 2009.〕〔("Sea fort put on the market for £800,000" ), ''Metro'', 12 October 2009, accessed 12 October 2009.〕 but was sold before auction, reportedly for more than £1m.〔(Historic Spitbank Fort sells for £1m ), ''Daily Telegraph'', 4 November 2009〕
Beginning June 4, 2002 the fort was used as a location for ''Banged Up With Beadle''. For six weeks British TV personality Jeremy Beadle was locked in its dungeons. Cameras followed him as he coped with survival, plus learning skills with a different member of the public each week. These skills were put to the test as a live insert each Saturday evening into ''Ant & Dec's Saturday Night Takeaway''. The fort was also featured on an episode of ''Most Haunted'' in series 8.
It has been a Scheduled Monument since 1967.〔(【引用サイトリンク】title=Spitbank Fort )〕
