Dolmen D20, together with dolmen D19, is located west of the village of Drouwen on the Steenhopenweg in the Dutch province of Drenthe. The dolmens are approximately 15.5 meters apart.
Dolmen D20 is attributed to the funnel beaker culture.
It is 11.3 meters long and 3.4 meters wide. The special thing about this dolmen is that the crown stones, which originally formed the base of the burial mound, are still largely preserved.
Five capstones of the original six remain. There is another gate capstone on the four gate stones.
Near the dolmens, an old cart track of a prehistoric road can be seen.
