England sea forts

Maunsell’s army sea forts were specifically designed to repel smaller aircraft flying in to attack Great Britain. Each fort consists of a cluster of smaller units arrayed in agroup. Each group had one spotlight tower and the rest of the units had guns  mounted all around to give maximum range. Each fort was connected by bridges  to the others in the cluster but was also structurally autonomous –  presumably in case one were to be successfully targeted and destroyed. Since  being decommissioned in the 1950′s, a number of these forts have been  used for pirate radio  broadcasting stations while others been converted into a luxury resorts.

Most of them are abondone after the war but some of them actually been converted intp luxury hotel, like the no man's land sea fort.
