Admiralty M-N Scheme, Naval defense system in Dover Strait, United Kingdom.
The Admiralty M-N Scheme was a defense system made of concrete and steel towers connected by submarine nets across the Dover Strait. The structure was designed to form a continuous barrier that would control shipping and prevent enemy vessels from passing through the channel.
The system was developed by the British Admiralty in 1917 to counter German U-boats during World War I. Only two towers were actually constructed, as the ambitious project was never fully completed.
The project represents British naval engineering innovation, demonstrating the nation's commitment to protecting maritime routes during wartime operations.
The two towers that were built stand in different locations, with one later converted into a lighthouse. Visitors should know that these structures sit in the water and can only be reached from specific vantage points on shore or by boat.
One of the towers was later converted into the Nab Tower lighthouse near Bembridge and continues to function as a navigation aid today. This transformation shows how British engineers adapted the original military structures for peaceful purposes.
