Roskilde is a city in Denmark, west of Copenhagen. Next to its harbor, the Viking Ship Museum has 11th-century vessels and an active boatyard. In its center, the Gothic, twin-spired Roskilde Cathedral holds the tombs of many Danish kings and queens. The nearby Museum of Contemporary Art sits in a former royal mansion. West of the city, the huge Land of Legends open-air museum recreates Stone Age and Viking life.
