Dunwich: drowned medieval port beach

Where: UK & Ireland · Europe · approx. 52.28, 1.63 (vicinity only)

Why this spot: Once a rival of London with churches and quays, lost to the sea from the 1287 storms; the medieval town lies offshore, the churchyard edge still erodes from the cliff

What turns up: hag stones, sea glass, coal, after storms: worked stone or medieval debris (report, do not keep human remains)

Access: Open / legal.

Open beach walking and shingle combing are fine; Greyfriars above is a Scheduled Monument, so no digging at the cliff, and any bones eroding from the lost churchyards must be left and reported
