 Between 500 and 1000 AD, Aker farm was one of the most important power centres in Norway, located just a few kilometres away from today's Hamar.Three coins found in Ringerike in 1895 have been dated to the time of Harald Hardråde and are inscribed "Olafr a Hamri".At some point, presumably after 1030 but clearly before 1152, the centre was moved from Aker to the peninsula near Rosenlundvika, what we today know as Domkirkeodden.
