Maritime archaeologists in Sweden have discovered a well-preserved shipwreck in the Baltic Sea that is believed to be the oldest known carvel-built ship in the Nordic region. The ship's design marks a turning point in shipbuilding history and could provide valuable insights into medieval naval technology and trade routes. The ship, designated Wreck 5, is larger than most medieval Scandinavian vessels and was dated to the 1480s through dendrochronological analysis. The discovery raises questions about Sweden's efforts to modernize its fleet during a time of European naval expansion.
