Dunge Coastguard Station is visible on Epoch 3 (1908) of the historic 1:2500 Ordnance Survey mapping [1], located less than 500m from the coastline at Lydd-on-Sea. The structures associated with the station are still apparent on Epoch 4 (1950), but they are not labelled as a Coastguard Station [2]. They are still visible on MasterMap (2009) where they are labelled as Coastguard Cottages [3].
The extent of the station was given a monument polygon during historic mapping enhancement as part of Phase 1 of the South East Rapid Coastal Zone Assessment Survey.
