The museum is located at the place of former Silkeborg Manor from 1767, the oldest building in town. It presents iron age archeological founds. The most famous items on display are the mummies of Tollund Man and Elling Woman, bog bodies found during peat digging in the nearby swampy area. Although aged 300 B.C., the head of Tollund Man is remarkably well preserved, including a peaceful facial expression and wrinkles.
