Examination of a 15th-century sunken vessel

Divers are investigating a well-preserved sunken 15th-century vessel off Häringe in the Stockholm archipelago. According to Euronews, it is considered the oldest medieval warship found in Swedish waters; the find may add to our understanding of Scandinavian shipbuilding.

Design features and historical context

The ship was built using carvel construction: the planking was laid flush, edge to edge, forming a smooth hull. Researchers note that this is the first known example of a vessel built this way in Sweden or Denmark. The sunken ship may be linked to historical conflicts between Sweden and Denmark around the year 1500.

What archaeologists are looking for

Archaeologists are documenting parts of the vessel buried under sediment and are searching for its galley, hoping to learn more about the crew's diet and daily life. The ongoing investigation is intended to help understand how medieval warships were built, how they were used in regional conflicts, and what life was like for sailors on board.
