Arolsen Castle is a baroque-style schloss in Bad Arolsen, Hesse, Germany. The castle is now a museum, and is still inhabited by Wittekind, Prince of Waldeck and Pyrmont and his family.
As a result, it continues to serve as a residence of the former ruling family of the Principality of Waldeck and Pyrmont. It was the birthplace of Princess Emma of Waldeck and Pyrmont, who became the Queen consort of the Netherlands during the late 19th century.
