Dolmen D45 is located in the Emmerdennen, a wooded area in the town of Emmen in the Dutch province of Drenthe.
This is the third-largest dolmen in the Netherlands. The dolmen is attributed to the funnel beaker culture. It is a large dolmen, which is located on a small hill and therefore towers above the surroundings. The dolmen is 18.5 meters long and 4.5 meters wide. Thirteen wreath stones are still there, twenty-five have disappeared. Originally there were twenty bearing stones and nine capstones. One of the six remaining capstones has boreholes. There are nineteen supporting stones left and the two keystones are also still present.
