In the Viking era, a rampart protected Århus, and in 1963 some archaeologists went digging to find whatever they could to learn of life in centuries past. The finds were impressive, including many artifacts, even a human skeleton. Remains of the town's Viking walls can still be seen. The most precious artifacts of the Viking era are displayed in the basement of Unibank, close to the cathedral. You'll find reconstructions of Viking houses -- that is, a stave church and one of the small pit houses found during the excavation at the site. Objects illustrate how life went on in this bustling merchant city from its foundation in about A.D. 900 until around 1400.
