You can't get to D26 by car and it's not that easy to find. Seen from Drouwen, it's on the other side of the N34. You can get there via a few narrow and poorly paved roads. The last 500 metres have to be done on foot. However, the search is worth it: At the edge of the forest you can see a medium-sized dolmen with five capstones, all neatly in place. The dolmen looks a bit low because the 12 side stones and 2 keystones have almost disappeared under the sand. As a result, it almost seems as if the capstones are resting on the ground. D26 is one of the 14 dolmens where one or more kerbstones can still be found. Here, 13 of the original 27 are still present. The 14 missing ones were marked with plumbs by Van Giffen. The 4 gate pillars that are still present show that this grave had a long entrance. The shape of the original hill is also still clearly visible. This dolmen was thoroughly investigated by archaeologists led by Dr. Jan Albert Bakker of the University of Amsterdam between 1968 and 1970, and not without results: On the cellar floor they found the remains of 160 pots. Furthermore, stone weapons and tools and amber beads. In front of the entrance they found a kind of sacrificial pit with 2 complete earthenware pots. D26 is the last dolmen that was investigated by archaeologists. As for further excavations, they have become very cautious. On the one hand because it is not expected that new excavations will lead to new insights, on the other hand because research inevitably causes destruction of the original situation. Future archaeologists may be able to prevent this with new techniques.
