What type of 600-year-old medieval cargo ship, the largest of its kind found, was discovered off Denmark in January 2026?

Off the coast of Denmark in January 2026, maritime archaeologists uncovered the remarkably preserved remains of a 600-year-old medieval cargo vessel. This significant find was identified as a cog, a type of ship that revolutionized trade in Northern Europe during the Middle Ages. Discovered in the Øresund, the strait between Denmark and Sweden, this particular wreck, named Svælget 2, is considered the largest cog ever found, offering unprecedented insights into 15th-century shipbuilding and seafaring.

Cogs were robust, single-masted sailing vessels characterized by their clinker-built sides and a flat bottom, which allowed them to navigate shallow waters and settle upright in harbors for easier loading and unloading. Developed in the North Sea region, these "super ships" were crucial for the economic development of the 14th and 15th centuries, enabling the efficient and low-cost transport of large quantities of goods. While earlier long-distance trade was often limited to luxury items, the immense cargo capacity of cogs, like the 300-ton Svælget 2, transformed trade patterns by making it feasible to ship everyday commodities such as salt, timber, bricks, and basic foodstuffs across vast distances.

The exceptional preservation of Svælget 2, found at a depth of 13 meters and shielded by sand, provides a unique opportunity for researchers. The wreck still retains traces of its rigging and even features a brick galley, the first of its kind found in a medieval Danish ship, suggesting a remarkable level of comfort and organization on board for its small crew. This discovery is a milestone for maritime archaeology, shedding new light on the scale and structure of medieval trade networks that bound Northern Europe together.
