The Vasa warship is a 17th-century Swedish vessel that is renowned for being the mightiest warship of its time. It sank on its maiden voyage on August 10, 1628, with about 30 of the 150 people aboard drowning. The ship was 226 feet long and carried 64 heavy cannons, making it an unprecedented armament for a battleship at that time. Often referred to as "the Titanic of Sweden," the Vasa is the world's only fully intact 17th-century warship. Today, it is housed in the Vasa Museum in Stockholm, where visitors can explore its history and significance.
