No Man’s Land Fort is a floating fort built off the coast of the Isle of Wight between the years 1867 and 1880 to defend Portsmouth from the French during the Napoleonic wars.
The fort is nearly 100 meters in diameter and rises 20 meters from the sea and is heavy framed with granite and steel walls.
Its water supply comes from a borehole sunk into the seabed and it has its own electricity generators. Its sunken inner centre are screened from the elements by a glass roof and it is now a luxury home with 2 helipads, indoor swimming pool, Jacuzzis, gym and two restaurants among other things.
