A 600-year-old viking ship discovered off the coast of Denmark

The Vikings, who dominated the northern seas for centuries, are known not only as bold—and often ruthless—explorers, but also as skilled shipbuilders. Recently, researchers managed to uncover a remarkable find: the world’s largest Viking ship, offering a unique insight into the history of medieval maritime trade.

For centuries, the Vikings’ name has been synonymous with seafaring conquests and legendary navigational expertise. These Scandinavian warriors excelled not only in combat but also in shipbuilding: their vessels were fast, light, and extremely durable. Thanks to this, they dominated the northern waters for centuries, established trade routes, and reached distant lands. Yet a new sensational discovery may rewrite what we know about medieval Viking seafaring.

The world’s largest Viking ship may have been found

As Popular Mechanics reports, archaeologists discovered the remains of the world’s largest so-called cog ship off the coast of Denmark. This extraordinary Viking ship has been named Svaelget-2 after the channel where it was found. Its size alone is impressive: nearly 28 metres long, 9 metres wide, and almost 6 metres high—far surpassing the dimensions of previously known medieval cargo vessels.

Experts believe the Viking ship was built around 1410 and lay buried on the seabed for some 600 years between Denmark and Sweden. The discovery occurred during a survey of the seabed ahead of construction work in a new district of Copenhagen.

A ‘super ship’ of the Middle Ages

Svaelget-2 is rightly described as a medieval “super ship,” as estimates suggest it could carry up to 300 tonnes of cargo—a remarkable feat for the 15th century. The Viking ship was therefore not only a military asset but also a key pillar of trade.

According to marine archaeologist Otto Uldum, a ship of this capacity points to a well-structured and complex trade network. Merchants knew exactly where their goods were in demand and planned their routes accordingly.
