Maritime archaeologists in Sweden have identified what may be the oldest carvel-built ship in the Nordic region.
The wreck was found in Landfjärden, south of Stockholm, at the end of February. It is believed to date back to the 1480s, possibly even the 1460s, according to the Vrak Museum of Wrecks.
Wreck 5: A remarkable shipwreck discovery
The ship, known as Wreck 5, is one of five found in the waters off Landfjärden. Measuring approximately 35 metres long and 10 metres wide, the vessel remains remarkably intact. Its frame still rises from the seabed, with both the sternpost and rudder standing upright, as confirmed by museum curator and project manager Håkan Altrock.
What makes Wreck 5 particularly significant is its construction technique. Unlike the traditional clinker-built ships of the time, which had overlapping planks, this vessel was built using the carvel method. This approach, where planks are laid edge to edge, created a smooth hull that allowed for larger and stronger ships. Maritime experts believe this innovation emerged due to the introduction of cannons on ships in the 15th century, as vessels required increased stability and durability to withstand enemy fire.
Analysis of the timber used in the ship’s construction indicates it was felled in either Möre, in the Kalmar region, or in eastern Blekinge. Though some of the other wrecks in Landfjärden were previously dated to the 1600s and 1700s, Wreck 5 stands out due to its age and significance in shipbuilding history.
“This ship represents a fascinating link between medieval and modern shipbuilding,” said Altrock. “It has the potential to provide us with valuable new insights into an important period in Sweden’s maritime history.”
The Vrak Museum’s team plans to apply for external funding to excavate Wreck 5 as part of a separate research project. The discovery is expected to shed light on how shipbuilding evolved in response to changing naval warfare and trade demands.
