The towns of Deal and Walmer have obviously grown and changed over the years. Existing streets were built on, layout changed and roads widened as the area grew and developed. Long established streets, buildings and alleyways vanished due to bomb damage during WW11 followed by a programme of re-building.
While providing some small areas of maps within our Streets, Alleys, Courts & Roads pages, and on some of the family pages, we haven’t a single large scale map on the site for you to view.

However, we use Kent County Council Heritage Maps

Or just for modern maps there is OpenStreetMap Wiki
