Six wrecks across a changing coastline<\/h2>\n\n\n\n
The ship remains were found during archaeological work that began in 2019, in and near Varberg\u2019s historic center. The team dated four wrecks to the Middle Ages or late medieval period, one to the 1600s, and one could not be dated.<\/p>\n\n\n\n
A 2025 report on three of the vessels<\/a> was written by Elisabet Schager with co-authors Anders Gutehall, John Evan Skole, and Edgar Wr\u00f3blewski. Schager said, “It will be very interesting,” adding that the team expects “a lot of exciting things” as the remaining analyses move forward.<\/p>\n\n\n\nFieldwork involved marine and archaeological specialists from Bohusl\u00e4n Museum, Visual Archaeology, and Cultural Environment Halland.

Wreck 2 comes from an oak sailing ship built in the second half of the 1530s using timber from western Sweden. Investigators recovered two connected hull sections from the starboard side plus scattered timbers, making it the most continuous structure in the group.<\/p>\n\n\n\n
The ship was built in “clinker” style, meaning the wooden planks overlap like shingles. It is a classic northern technique for building sturdy hulls.<\/p>\n\n\n\n
Researchers found burn traces on a protective strip along the hull. The report says the ship may have been burned before it sank, but the cause is still unclear.<\/p>\n\n\n\n
A “berghult” that took the hits<\/h2>\n\n\n\n
That protective strip is called a “berghult,” and it works a bit like a wooden bumper. When a ship nudges up to a dock or scrapes along a pier, the strip helps take the impact instead of the hull itself.<\/p>\n\n\n\n

Berghult is often linked with “carvel” construction, where planks sit edge to edge for a smoother surface, but it can appear on clinker ships too. The report points to the Osmund wreck<\/a>, studied by Vrak, Sweden\u2019s Museum of Wrecks, and to the Riddarholm ship<\/a> described by Stockholm\u2019s Medieval Museum.<\/p>\n\n\n\nWreck 5 and a 1600s seaway<\/h2>\n\n\n\n
Wreck 5 has a lot in common with Wreck 2, including oak from the same region and the same clinker style. Tree-ring dating suggests its wood was cut sometime in the 1600s.<\/p>\n\n\n\n
Experts think ships like these sailed outside the medieval cities of Varberg and Ny Varberg and may have ranged across the Baltic Sea. It is a reminder that the Baltic was a working corridor of trade for centuries.<\/p>\n\n\n\n
The tunnel schedule shaped the recovery, and Wreck 5 had to be lifted quickly. The report notes that additional parts may still be buried beyond the excavation area.<\/p>\n\n\n\n

Wreck 6 differs from the others because it was built in carvel style, with planks laid edge to edge and fastened to a frame. That approach tends to create a smoother outside surface, and it can support different hull shapes than clinker building.<\/p>\n\n\n\n
It is also the only one of the closely studied wrecks with a preserved keel, the long beam that acts like a backbone. The report says the grooved keel and other details hint at Dutch shipbuilding tradition.<\/p>\n\n\n\n

Wrecks 3 and 4 are dated to the 1300s and match the flat-bottomed “cog” style used for medieval cargo transport. They were designed for hauling goods in ports and shallow coastal waters.<\/p>\n\n\n\n
