“One large chambered cairn, at Minninglow on a high hilltop between Parwich and Elton, started life as a small mound with a chamber. It was later enveloped in a long cairn with at least four chambers entered from the sides. Later still it was enlarged again, to make it into a massive near-circular mound. There are four or five such “great barrows” in the region, each about 40m (131ft) across, which were probably the local equivalents of later Neolithic mounds such as Silbury Hill and Duggelby Howe (Yorks Wolds).“EH – Peak District John Barnatt and Ken Smith.
