1:300 Red Sands Fort (U6) for Cruel Seas

UPDATE 01.14.19: I've rescaled it, as the first time it was almost 2x as big as it should be.

There are seven towers in the Red Sands group, at the mouth of the Thames Estuary. These towers were previously connected by metal grate walk-ways. In 1959 consideration was given to refloating the Red Sands Fort and bringing the towers ashore, but the costs were prohibitive. In the early 21st century there were threats that the fort could be demolished so a group called Project Redsands was formed
