Dunwich, Britain's Atlantis

A city the size of old London — eight churches, a mint, a fleet — was eaten street by street by storms in the 1200s and 1300s. It's still down there, mapped by sonar in water too dark for a diver's eyes.editorial

The Story

What is claimed · what is sourced · what is still disputed

Dunwich was one of the great ports of medieval England, eight churches, a mint, a fleet. The storms of 1286 and 1347 ate the coast from under it, street by street, until the last tower went over the cliff. The city lies just offshore in water like cold tea; sonar has mapped its ruins where divers' eyes are useless. Locals say you can hear the bells under the waves. The sonar, less romantic, found the church towers.

What remains open

  • No period map of the site has surfaced.
  • No contemporary press coverage has been found.
  • Sonar has found the church towers. It hasn't answered what else of medieval Dunwich survives intact in water too murky to see by hand.

The lure: A drowned medieval city the size of old London
