D20

D20 is a hunebed, a type of dolmen, in Drenthe in the Netherlands. It stands with hunebed D19 about 15,5 meter from each other, west of the village of Drouwen along the Steenhopenweg, close to a viaduct constructed in 2006 beneath the N34. The monument is attributed to the Funnel Beaker culture and is dated by typological estimate to 3500 BCE to 2800 BCE.

D20 is 11,3 meter long and 3,4 meter wide. Most of the kerb stones that once formed the foot of the burial mound remain, although Van Giffen replaced six missing stones with concrete markers. Five of the original six capstones survive, and a portal capstone still rests on the four portal stones. An old prehistoric cart track is visible near D19 and D20.

The Dutch government bought D19 and D20 from the Rolde municipal council in 1847 after their sale caused concern. J. Craandijk described both monuments in 1879. Archaeological investigation began at them in 1912, when Jan Hendrik Holwerda excavated the two hunebedden. The finds indicated that D19 and D20 belonged to the same period. Van Giffen examined D20 in 1961-1962, finding three Funnel Beaker pots placed inside one another outside the kerb-stone circle. The monument was restored in 1998.

William Collings Lukis and sir Henry Dryden surveyed D20 in July 1878 for the Society of Antiquaries. Their measurements, descriptions and watercolours were not published at the time, but their work was issued in 2015 by Drentse archaeologist dr. Wijnand van der Sanden. Their record shows thirteen supporting stones and five capstones, with a fragment of a sixth supporting stone on the east side. The mound had recently been lowered and was still about 20 meter across.
