Dolmen D12 is a portal grave. It is located southwest of Eext in the Dutch province of Drenthe. The dolmen was investigated and restored in 1952.
It is quite remote on the Kamp Akkers, near Eext. The dolmen can only be reached via a sandy path, which turns into a grassy path.
The dolmen D12 is one of the smaller Dutch dolmens. It is 6.8 meters long and 2.8 meters wide.
Several stones from the dolmen have been broken. The three existing capstones fell into the crypt. For a long time, there was a tree against this dolmen, but it has been sawn to the ground.
The dolmen was investigated in 1918 by the archaeologist Albert van Giffen. He mentions three capstones that rest on the three bearing stones. There is also a keystone.
Johannes van Lier mentions that urns in the upside-down position were found by a careful hand. A collar-neck bottle has also been found. They are depicted in drawings from 1760.
