The Giebichenstein near Stöckse, Germany, in the district of Nienburg, Lower Saxony, is one of the largest erratic boulders of northern Germany. It weighs around 330 tonnes (730 thousand pounds). A picture of the Giebichenstein is part of the emblem of the Stöckse municipality.
There is the supposition that during Wolstonian Stage the stone was deposited by glaciers as a part of a moraine. Near the Giebichenstein there are the remains of a dolmen, and at the stone itself there were found the remains of a Stone Age hunter's camp.
