You will almost certainly encounter hunebed D51 Noord Sleen en route to its much better preserved twin, D50, which lies about 100 metres farther along on the opposite side of the road (Hunebedweg).
D51 is very much the poor relation in this hunebed pair: it is somewhat smaller (at 12.3 × 3.5 metres), completely lacks a ring of kerbstones, and has clearly been the target of stone robbers over the ages. All but one of the original 14 sidestones remain in place though, but of the complement of capstones, only two of the assumed seven originals are still to be seen, one still supported and the other partly slumped into the crypt. There is an entrance portal with three of its original four stones still present.
Following Julian's instructions in The Megalithic European we quickly located D50 and D51 at the tiny hamlet of Noordsleen, near Emmen.
Our footsteps crunching the 150ms up the icy farm track towards the copse in which they lie, the first hunebed you reach is D51. With only three capstones remaining, this site feels a bit trashed, but with snow on the stones and the huge flat fields all around glistening it felt exciting and special to be there, as this was both Moth's and Cleo's first hunebed.
