Dymchurch Redoubt was built near Dymchurch, Kent,between 1804 and 1810 to support the associated Martello Towers. Like its twin Eastbourne Redoubt it was designed as a barracks and supply depot for the towers, and armed with 11 guns. During WWII many pillboxes and observation positions were added to the parapet, and its current use by the Army prevents access.
Two redoubts were constructed into the south coast Martello chain to act as supply depots for the local Martellos, and were originally described as 'eleven-gun towers'.
Dymchurch also underwent significant re-fortification during the Second World War, bunkers and pillboxes adorning its parapets.
On the western extreme of the Hythe Ranges, during the 1970's the Redoubt was being used by the British Army for training soldiers in the art of street-fighting.
