History of the wreck
The wreck was reported to the National Museum of Denmark after a breath-hold diver found it in 1975. It contained an exceptional assemblage, including 109 English gold nobles, other coins, ceramics, cordage, leather, textiles, wooden objects and animal remains. The excavation was directed by Ole Crumlin-Pedersen under strict security because of the gold.
Dendrochronology gave a terminus post quem of AD 1372, and the coins indicate a loss probably between 1377 and 1380. The coins placed in the mast step and the origin of the timber suggest that the ship was built in the region of Gdańsk, then in the territory of the Teutonic Order (Bonde and Jensen 1995).
It is one of the cog finds compared by Hans Jeppesen with the Kollerup cog (Jeppesen 1979).
