Osnabrück Hünenbetten

Before Germany’s past became inextricably linked with the events of the last few hundred years, its inhabitants were largely comprised of pagans. Modern day Osnabrück was once the sight of a major pagan temple, which had occupied the space since ancient times. When Charlemagne set out on a tirade to convert the inhabitants of the region to Christianity, a bloody massacre took place here. Nothing good ever comes from desecrating the sacred grounds of the natives, however. To this day, there have been countless reports of poltergeist in the area, particularly on the solstices. Orbs have been sighted and many claim the remaining rock formations become stained with blood.
