Grønnegade Runddysse is a dolmen dating back to the Neolithic era located on the Danish island of Zealand. The dolmen sits at the edge of a field, next to a road and is visible from the road. The mound that surrounded the dolmen still exists but the top has been destroyed due to ploughing and erosion throughout the centuries. This now leaves the greatly exposed dolmen behind and visible. The dolmen consists of one large capstone being supported by six support stones. Two other stones can be found in front of the dolmen. Further down the road one can find and see another Neolithic dolmen.
