The Maunsell Fort

The Maunsell Fort are armed towers built in the Thames Estuary during the Second World War to help defend the United Kingdom. They were operated as army and navy forts and named after their designer, Guy Maunsell. Their purpose was to provide anti-aircraft fire within the Thames Estuary area.

With a new fascination of bunkers, Max here goes in search of the Maunsell Fort off in the Thames Estuary.
