Hunebed D8 Kniphorstbos is a really nice, totally complete hunebed, lying in attractive woodland, slightly more than a kilometre west of the town of Annen, in Drenthe.
Following botched attempts at restoration in the second half of the 19th century, D8 was fully restored in 1952. Now it is a particularly fine medium-sized hunebed, boasting eight sidestones and two endstones: with all four of its original capstones in place.
Bus 58 from Assen Station to Groningen takes you to Annen in 27 minutes. Be sure to exit at the bus halt named 'Hunebed' on Zuidlaarderweg (right beside hunebed D9 Noordlo in Annen). Now walk about 100 metres northwest, past the roundabout, and turn left (west) along Schipborgerweg for 600 metres—then follow the pedestrian/cycle underpass below the N34 highway. On the far side of the N34 you emerge in woodland. Continue to walk on in the same direction, along the woodland path, until you reach the 2nd crossroads (after another 250 metres or so) and turn left (south). About 50 metres on, in a clearing on your left, is D8 Kniphorstbos.
