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 no longer exists now leaving the greatly exposed dolmen behind and visible. The dolmen consists of one large capstone being supported by four support stones. Further down the road one can find and see another Neolithic dolmen.
