Ever since I first heard its story on television as a small boy I have been interested by the history and fate of Dunwich, the once sizeable Suffolk town which has been inexorably washed away by the North Sea.
Last Monday The Times had a report on the latest survey of the engulfed areas of the town. that I cannot link to, being unavailable without a subscription. However I have found a report on the latest work at http://www.touchingthetide.org.uk/our-projects/underwater-dunwich/ and there is a website devoted to the town and its history at Dunwich - The search for Britain's Atlantis
The Wikipedia article Dunwich is also a useful account, and like the others illustrated.
