D21

Hunebed D21 is a portal tomb near Bronneger in Drenthe, Netherlands. It is one of five hunebedden in the area and the most important of them in terms of archaeological finds. A nearby monument, D22, is so close that the pair are sometimes called twins. D23, D24 and D25 form another group at a short distance.

The tomb has three large capstones and eight originally supporting stones, although a large beech tree now takes the place of one support. Two closing stones and a portal stone are also present, with only their tops rising above ground. The monument measures 7,7 meter long and 2,9 meter wide. Its chamber floor is 6,50 meter by 2,20 meter, and the chamber height varies from 1,50 to 1,70 meter.

D21 is attributed to the Funnel Beaker culture and is dated typologically to 3500 BCE to 2800 BCE. Dr. van Giffen investigated it in 1918 and found several floor layers containing artefacts, including more than 600 pieces of pottery dated to 3400 v.Chr. He found a missing supporting stone about one meter below ground and concluded that it had probably fallen while the tomb was in use. The monument was restored in 1960-1961.

In July 1878, William Collings Lukis and sir Henry Dryden documented D21 for the Society of Antiquaries. They called it hunebed I and recorded nine supporting stones, three capstones and an entrance between the second and third supporting stones on the south side. Their work was published in 2015 by Drentse archaeologist dr. Wijnand van der Sanden, who judged it to be of high quality. A large tree beside D21 is also a notable visual feature.
