The Mortar Wreck: a mid-thirteenth-century ship, wrecked off Studland Bay, Dorset, carrying a cargo of Purbeck stone

Throughout the medieval period, thousands of ships plied their trade around England's coasts. History documents numerous lost ships, and more would have sunk without record, yet very few wrecks dating between the tenth and fifteenth centuries AD have previously been discovered in English waters. The author reports on one of the first of such finds—the wreck of a clinker-built sailing vessel, dated to c. AD 1250, that was carrying a cargo of Purbeck stone. Examination of the ship and its cargo reveals new insights into shipping and the Purbeck stone trade in the thirteenth century.
