Vasa

Vasa was a Swedish royal warship that capsized and sank in Stockholm harbor on her maiden voyage on 10 August 1628, barely a nautical mile from her berth, when wind caught her tall, overgunned, and dangerously unstable hull. Forgotten for over three centuries, she was located and salvaged almost intact in 1961, preserved by the cold, brackish, low-oxygen Baltic water. After decades of polyethylene glycol conservation she is displayed at the Vasa Museum, the best-preserved seventeenth-century ship in the world.
