Skansen was the first open-air museum in the world. Skansen is also a zoological park specialising mainly in Scandinavian fauna. It is located on the island of Djurgården, a royal park near the centre of Stockholm. Skansen was founded in 1891 by Artur Hazelius (1833-1901) for the purpose of showing how people had lived and worked in different parts of Sweden in times gone by. Over the years about 150 historical buildings have been moved here from nearly every part of Sweden. Most of them date from the 18th and 19th centuries. Visitors to the houses and farmsteads are met by hosts and hostesses in period costume. They often demonstrate domestic occupations, such as weaving and spinning.
