D31

The Großsteingrab Exloo-Zuid is a poorly preserved megalithic gallery grave belonging to the western group of the Late Neolithic Funnel Beaker culture. It lies in the Hunzebos woodland south of Exloo, a district of Borger-Odoorn in Drenthe, Netherlands, and carries the Van-Giffen number D31.

The burial chamber is 7 m long and 3,3 m wide, within a clearly recognizable oval mound. It originally had four pairs of side stones, two end stones, and four capstones. Only one capstone survives, lying inside the chamber, while two stones from the southern long side are missing. Unlike most Dutch hunebedden, its entrance was at the eastern end of the southern side rather than in the middle, with a short passage originally formed by two stones. Concrete fills the sockets of the missing chamber and passage stones.

The tomb was first mentioned in 1818. Leonhardt Johannes Friedrich Janssen visited it in 1847 and published the first general overview of Dutch hunebedden with descriptions and schematic plans in the following year. William Collings Lukis and Henry Dryden documented it in 1878, Albert Egges van Giffen recorded the monument in 1918, and it was restored in 1952. During a smaller investigation in 1965, the sockets of the passage stones were discovered. The monument has been a protected national heritage site since 2004 and was recorded by photogrammetry for a 3D atlas in 2017.

Based on a typological estimate, the monument dates from 3500 to 2800 BCE. More broadly, the megalithic tombs of northern Germany and the Netherlands are associated with the Funnel Beaker culture, while the style known as Nordic megalithic architecture developed between 3500 and 2800 BCE. Dutch hunebedden were later reused by the Single Grave and Bell Beaker cultures and, less extensively, during the Middle Ages.
