The Gnarrenburg dolmen (also call Steingrab im Eichholz) is a Neolithic megalithic complex. It originated between 3500 and 2800 BCE and was constructed by the people of the funnel beaker culture.
The dolmen is located north of Gnarrenburg, in the Eichholz state forest, in the Elbe-Weser triangle in a pine forest, not far from the forest road that leads from Gnarrenburg to the Brillit district, in the Rotenburg district in Lower Saxony, Germany.
