In archaeology, a ring ditch is a trench of circular or penannular plan, cut into bedrock. They are usually identified through aerial photography either as soil marks or cropmarks. When excavated, ring ditches are usually found to be the ploughed‐out remains of a round barrow where the barrow mound has completely disappeared, leaving only the infilled former quarry ditch. Both Neolithic and Bronze Age ring ditches have been discovered.
