The Vasa Museum () is a maritime museum in Stockholm, Sweden. Located on the island of Djurgården, the museum displays the only almost fully intact 17th-century ship that has ever been salvaged, the 64-gun warship Vasa that sank on her maiden voyage in 1628. The Vasa Museum opened in 1990 and, according to the official website, is the most visited museum in Scandinavia. Together with other museums such as the Stockholm Maritime Museum, it belongs to the Swedish National Maritime Museums (SNMM). History From the beginning of 1961 to 1983, Vasa was housed in a temporary structure called Wasavarvet ("The Vasa Shipyard") where she was treated with polyethylene glycol. Visitors could only view the ship from two levels and the maximum distance was only 5 m (17 ft). In 1981, the Swedish government decided that a permanent Vasa museum was to be constructed and a competition for the design of the museum building was organized. A total of 384 architects sent in models of their ideas and the final winners were Marianne Jakobbäck and Göran Månsson with Ask ("box"). The construction of the new building began on and around the dry dock of the old naval yard with an inauguration ceremony hosted by Prince Bertil on 2 November 1987. Vasa was towed into the flooded dry dock under the new building in December 1987, and during the summer of 1989, when visitors were allowed onto the construction site, 228,000 people visited the half-finished museum. The museum was officially opened on 15 June 1990. So far, Vasa has been seen by over 25 million people. In 2017, the museum had a total of 1,495,760 visitors. The main hall contains the ship itself, and various exhibits related to the archaeological findings of the ships and early 17th-century Sweden. Vasa has been fitted with the lower sections of all three masts, a new bowsprit, winter rigging, and has had certain parts that were missing or heavily damaged replaced. The replacement parts have not been treated or painted and are therefore clearly visible against the original material that has been darkened after three centuries under water. The new museum is dominated by a large copper roof with stylized masts that represent the actual height of Vasa when she was fully rigged. Parts of the building are covered in wooden panels painted in dark red, blue, tar black, ochre yellow and dark green. The interior
