D54 Havelterberg is the name given to a Neolithic passage grave located in the Netherlands. The site is one of the many well-preserved passage graves in the country. The megalithic structure is located by the road and is clearly visible from the road when driving by. The mound that covered the site has been removed by either erosion or ploughing and now the 12 m long passage and 7 capstones are revealed.
Another passage grave is further down the road.
