The summit of Mam Tor is encircled by a late Bronze Age and early Iron Age univallate hill fort. Radiocarbon analysis suggests occupation from around 1200 BC. The earliest remaining features are two Bronze Age burial mounds, one just below the summit and the other on the summit itself, though now buried under the paving. At a later stage over a hundred small platforms were levelled into the hill near the summit, allowing inhabited timber huts to be constructed. The hill fort and burial mounds are a Scheduled Ancient Monument.
