Vasa (or Wasa) is a Swedish warship built between 1626 and 1628. The ship foundered and sank after sailing about 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 lane just outside the Stockholm harbour. Salvaged with a largely intact hull in 1961, she was housed in a temporary museum called Wasavarvet ("The Wasa Shipyard") until 1988 and then moved to the Vasa Museum in Stockholm. The ship is one of Sweden's most popular tourist attractions and has been seen by over 29 million visitors since 1961. Since her recovery, Vasa has become a widely recognized symbol of the Swedish "great power period" and is today a de facto standard in the media and among Swedes for evaluating the historical importance of shipwrecks.
