Vasa

Vasa (previously Wasa) ( Swedish pronunciation: [²vɑːsa] ) 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 ("The Vasa Shipyard") 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.

The ship was built on the orders of the King of Sweden Gustavus Adolphus as part of the military expansion he initiated in a war with Poland-Lithuania (1621–1629). She was constructed at the navy yard in Stockholm under a contract with private entrepreneurs in 1626–1627 and armed primarily with bronze cannons cast in Stockholm specifically for the ship. Richly decorated as a symbol of the king's ambitions for Sweden and himself, upon completion she was one of the most powerfully armed vessels in the world. However, Vasa was dangerously unstable, with too much weight in the upper structure of the hull. Despite this lack of stability, she was ordered to sea and sank only a few minutes after encountering a wind stronger than a breeze.
