Dolmens D28 and D29 - Buinen

A bit outside Borger, on the road to Buinen, you will find hunebed pairs D28 and D29. Why some dolmens were built in pairs has never been made clear, although there are several theories about it.

D28 still has 3 capstones and all 8 supporting stones and 2 keystones. Professor Dr Van Giffen rated this hunebed, despite missing some capstones with a "is in good condition". In the grave of D28 in 1927, Van Giffen found two spirals of copper wire, the oldest metal jewellery ever found in Dutch soil. These ornaments are part of the collection of the Drents Museum in Assen.

No scientific research has ever been carried out in the basement of D29. The cover mound is still intact; the professor therefore described the condition of this tomb as "in fairly good condition". The peculiarity of this grave is that this hunebed contains two very flat capstones, both with an unnaturally smooth side. It is possible that this was originally one large stone that the hunebed builders split. They might have done this by driving wedges into crevices or by alternately heating the stone with fire and cooling it again with water.
