Groß Steinum am Dorm, located between Königslutter and Helmstedt, is a village that lives up to its name. Mighty tuber quartzite blocks characterize the townscape. Wippstein and Bockshornklippe form striking, legendary rock formations on the edge of the old village center, the church is visible from afar on rocky ground and at least two megalithic tombs from around 3500 BC are likely to make by archaeological investigations in its neighborhood. The monumental tombs of large blocks of stone were common burial places of a large family or a clan. Where today lies Gross Steinum, was about 70 million years ago (Upper Cretaceous) a delta, which poured its sands westward into the Lower Saxony basin. At the turn of the Upper Cretaceous / Tertiary rose the salt dome in Beienrode / Dorm. In the following period lime-containing basic waters (pH value> 7) flowed from the dorm ago by the salt rise inclined quartz sands and dissolved shares of the same. The silicic acid dissolved in the pore water was precipitated again around the quartz grains when it encountered acidic waters (pH <7) of the former lowland, and in places formed the "tuber quartzite" from the loose sands. Their sparkling in the sun is due to light reflection of the crystal surfaces of the further grown quartz grains. The quartzite is hardly usable as a building block, because it can not be processed due to its hardness. Quartzite is occasionally used only as a refractory industrial raw material. Therefore, the Bockshornklippe has been preserved after the surrounding loose quartz sand was exploited as a building material. In six stations, the construction of a megalithic grave from the selection of stones to the outer design of the monument is traceable. For station 1 titled "Building material tuber quartzite", some particularly impressive and characteristic blocks of the Groß Steinumer tuber quartzite were put together. Station 2 "Moving Stones" is dedicated to the transport of large blocks of stone, as he would have with the technical possibilities of the Neolithic
can be mastered. Shown is the principle of roles and rails. "Brick up stones" is the title of Station 3, which represents the erection of the wall or support stones of the burial chamber.
