Maunsell Towers


From the Steam Geek archives-

The Maunsell Towers were set up to provide anti aircraft defence in the Thames Estuary during World War Two. Each “fort” comprised of one Bofors tower, a control tower, four gun towers and a searchlight tower. Three forts were built Nore Army Fort, the Red Sands Army Fort and the Shivering Sands Army Fort, of which the latter two still stand, more or less.
