A short drive south of Aarhus is the superb new Moesgård Museum. 

Built on the grounds of the Moesgård manor house where the original museum was housed, this well designed attraction opened in the autumn of 2014 and offers a comprehensive account of Denmark's history from the Stone Age to Viking times. 

A particular attraction is the Grauballe Man (Grauballemann), a corpse dating back more than 2,000 years that was found perfectly preserved in a nearby bog.
