During the Second World War, the British government constructed offshore anti-aircraft installations to extend protection beyond the range of land-based guns and radar. One of these forts is reportedly going to be converted into a luxury resort:
The Maunsell Forts built to defend the British Isles from Nazi invasion are in line for an upmarket make-over.
Billed as the next top-notch luxury resort, the forts will come complete with executive apartments, a helipad and even a spa at sea.
The Second World War era forts off the coast of Kent were constructed in 1943, and operated by both Army and Navy personnel.
