In Moesgård I've found quite a few of interesting things: - museum with expositions of: runic alphabet, Danish history, polar expedition to Greenland, - Grauballe Man (main thing to see, in the museum), - palace, unfortunately closed for turists, - forests and fields nice to exlore, - water mill with downy cache guardian, - reconstruction of four Danish buildings from differend epochs.
If anyone would be in Århus the place is definatelly worth seeing. Reserve at least half of a day. There's a lot to be seen.
