Skokloster Castle is located on Lake Mälaren between Stockholm and Uppsala. It was built in the Baroque style between 1654 and 1676 by the wealthy military commander and count Carl Gustaf Wrangel. The castle was designed by architect Nicodemus Tessin the Elder. When Wrangel died, the castle passed into the hands of the Brahe family, and then, after 1930, became the property of the von Essens. In 1967 the castle and its contents were sold by the family to the Swedish government; since then it has been open as a museum.
