Summary
- Largest medieval cog ship discovered off Copenhagen.
- Ship, named Svælget 2, was built in 1410.
- Remarkable preservation includes rigging and galley.

Danish archaeologists have announced the discovery of the world's largest medieval cog ship, named Svælget 2, off the coast of Copenhagen. The vessel, which had been underwater for approximately 600 years, was found in the Øresund strait during surveys for a new development.
Built in 1410, Svælget 2 measures around 92 feet long and 30 feet wide. Tree-ring analysis indicates its timber originated from regions now in Poland and the Netherlands. This impressive cog is noted as the largest example of its type ever discovered globally, highlighting its significance as a backbone of medieval trade.
The ship's remarkable state of preservation is attributed to seabed sand. Astonishingly, its rigging and a brick-built galley, where crew cooked meals, were found intact. Personal items like dishes and shoes were also recovered, suggesting sailors lived in relative comfort.
