D45

Großsteingrab Emmerdennen is a megalithic passage grave in the Emmerdennen woods, east of the centre of Emmen in the Dutch province of Drenthe. It is also known as D45, a Van-Giffen catalogue number. The site lies within an area containing many other Großsteingräber and is reached by a forest path.

The grave is a large passage grave oriented east-northeast to west-southwest and built on a dune. Its oval enclosure retains 13 stones, while the sockets of 25 missing stones were filled with concrete during restoration in 1957. The oval chamber is 18.5 m long and 4.5 m wide, built from nine wall stones on the northern side, eleven on the southern side, and an end stone at each short side. Six of the original nine capstones survive, with the three eastern ones missing. One capstone has a row of wedge-shaped holes.

First recorded on the Hottinger-Karte, created between 1788 and 1792, the grave was visited in 1809 by King Ludwig Napoleon and Petrus Hofstede. It was inaccurately restored in 1870 and badly damaged in 1885. Albert Egges van Giffen documented it in 1918, investigated and restored it in 1957, and later recorded it in his atlas of Dutch megalithic graves. It has been a National Monument since 1983. A project involving the province of Drenthe, the Reichsuniversiteit Groningen and the Stiftung Gratama recorded the surviving Dutch Großsteingräber by photogrammetry in a 3D atlas in 2017.

The grave belongs to the western group of the Funnel Beaker culture and is dated by typological estimate to 3500 BCE to 2800 BCE. Excavation by van Giffen found small quantities of cremated human bone weighing 28.2 g, belonging to one individual whose age and sex could not be determined. The finds also included 20 g of burned animal bones and an unburned cattle bone, one fragment of which may have been used as a chisel.
