First reported 1711 Ludolph Smids Schatkamer der Nederlandsse Oudheiden
D29 lies with its twin D28 in a large wooded grove just off the road from Borger to Buinen. Sitting in a peaceful and contemplative milieu, it is distinguished by a partially collapsed capstone that resembles a broken heart. Borger folk legend has it that the hunebed builders threw stones tp each other from one place to another over the heath, first from Buinen to Borger, and from there to Drouwen. Curiously, this reflects what archaeologists have learned about the cultural dispersion pattern.
