These two hunebeds are the pride of Noordsleen. The D51, on the left, is a small covered alley topped by three slabs (four of them have disappeared). Further on on the right, the D50, shaded by the huge oaktree growing in its centre, is better preserved. Five tables are still in place there as well as the oval crown of standing stones. To the south, the pillars at the entrance are still visible though worn.
