Grønjægers Høj or Grønsalen (meaning Hill of the Hunter Grøn, or King Grøns Hall) is one of Denmark's largest megalithic complexes. It is located in the southwest of the Danish island of Møn.
Grønjægers Høj is ascribed to the funnel beaker culture and is dated to about 3500 BCE. It is about 100 metres long and 10 metres wide and is surrounded by 134 stones and thus almost complete. In the barren bed, about 1.5 metres above the surrounding area, there are three small longitudinal chambers about 0.7 meters wide and 1.7 meters long. Two belong to the oldest type of Urdolmen (dolmens without access). The third chamber has a lowered end stone (bottom left in the picture) that allows access. Two of the chambers, built from four bearing stones, no longer have a capstone. The third chamber has a roof-like capstone. No archaeological finds have been made in any of the chambers.
