16th-century shipwreck older than Vasa found in Sweden's Kalmar Strait

A 16th-century shipwreck discovered in the Kalmar Strait, Sweden, is older than the legendary Vasa warship. The wreck was found accidentally in autumn 2025 by the Swedish Navy's submarine rescue vessel HMS Belos during routine military exercises. Dendrochronological analysis dates its construction to the late 16th century, about 30 years before the Vasa (built 1626–1628). The ship lies at 20 meters depth, measures 20 meters long and 6 meters wide (far smaller than the Vasa's 69 by 11.7 meters). Preserved by the cold, low-oxygen brackish waters of the Baltic Sea, the wreck is heavily degraded but offers rare archaeological insights into Renaissance-era Swedish navigation. The site is protected by a conservation plan led by the Kalmar County Museum; anchoring, fishing, and diving are prohibited. No images or videos have been released pending investigation. The ship's identity, origin, and sinking circumstances remain unknown.
