A historic fort built off the south coast to repel a French invasion is being marketed as a luxury nine-bed home and has seen its price slashed to £3million.
Owners have submitted plans to change Spitbank Fort from it's existing use as a hotel as they see it as unsustainable and have reduced the price from £4million.
The site is one of a chain of 19th century Royal Commission sea forts located in the Solent and is less than a mile off the mainland coast of Portsmouth.
