D51

D51, also known as hunebed D51, is a dolmen on the Hunebedweg, northwest of Noord-Sleen in Drenthe. It lies a little south of D50, on the opposite side of the same road. Following the construction of the N381, the Hunebedweg became a dead-end road.

The monument is heavily damaged and much smaller than D50 because only three of its seven capstones remain. Those capstones are damaged. Fourteen supporting stones and three portal stones still survive. The dolmen measures 12,3 metres long and 3,5 metres wide. It is attributed to the Funnel Beaker culture and is dated by typological estimate to 3500 BCE to 2800 BCE.

D51 already appears on the Hottingerkaart of 1788-1792. During the 19th century, the State of the Netherlands bought it from the markegenoten of Noord-Sleen. Van Giffen described it as being in a very battered condition and recorded fragments of the capstones and the presence of three portal stones. The dolmen was restored in 1961.

Monuments of this kind in northern Germany and the Netherlands were built by the Funnel Beaker culture, about 4100 to 2800 BCE. The style known as Nordic megalith architecture emerged between 3500 and 2800 BCE. In the Netherlands, hunebedden were built between 3470 and 3250 BCE by the western group of the Funnel Beaker culture and used until about 2760 BCE.
