The Swedish warship Vasa sank shortly after departing Stockholm on her maiden voyage to take part in the Thirty Years' War.

Vasa is a Swedish warship built between 1626 and 1628. The ship sank after sailing roughly 1,300 m (1,400 yd) into her maiden voyage on 10 August 1628. She fell into obscurity after most of her valuable bronze cannons were salvaged in the 17th century, until she was located again in the late 1950s in a busy shipping area in Stockholm harbor. The ship was salvaged with a largely intact hull in 1961 after spending 333 years on the seabed. She was housed in a temporary museum called Wasavarvet until 1988 and then moved permanently to the Vasa Museum in the Royal National City Park in Stockholm. Between her recovery in 1961 and the beginning of 2025, Vasa has been seen by over 45 million visitors.
