Medieval ship discovered off Copenhagen may be the world’s largest cog
Summary
Medievalists.net reports the discovery of Svælget 2, a large medieval cog found off Copenhagen, potentially the world’s largest of its type. The vessel, built around 1410 with timber from Pomerania and the Netherlands, measures about 28 meters long, 9 meters wide, and 6 meters high, with an estimated 300-ton cargo capacity, and features unusually well-preserved rigging and a brick galley. The find sheds light on late medieval trade networks, shipbuilding at scale, and provisioning on merchant vessels, with conservation underway at the National Museum of Denmark.
