D36

The Großsteingräber bei Valthe-Oost are two megalithic burial monuments at Valthe, a district of Borger-Odoorn in the Dutch province of Drenthe. They are also known as hunebedden and carry the Van-Giffen numbers D36 and D37. The monuments lie just south of Valthe along the Hunebedweg, with D37 about 25 m east of D36.

D36 is an east-southeast to west-northwest aligned passage grave with a 7.9 m-long chamber. Five pairs of side stones and one closing stone at each end once framed it, but one stone is missing from the southern side. Four of its original five capstones survive, one lying outside the chamber. The entrance is between the second and third southern stones, with only one stone remaining from the passage.

D37 has the same alignment and a chamber measuring 11.4 m long and 3.7 m wide. It originally had six pairs of side stones and a closing stone at each end; one stone from each long side is now missing. Three of its six capstones remain inside the chamber, and the easternmost has broken into two pieces. Its entrance lies between the second and third southern stones, while the presence of an entrance passage is uncertain.

The monuments are dated by typological estimate to 3500 BCE to 2800 BCE. They were recorded on the Hottinger-Karte between 1788 and 1792 and examined by Leonhardt Johannes Friedrich Janssen in 1847. Willem Pleyte and Jan Goedeljee photographed them in 1874, and detailed records were made in 1878. Albert Egges van Giffen documented both in 1918. Restorations took place in 1952, and photogrammetric recording was carried out in 2017.
