Description :
An exceptionally rich area of diverse features related to patching and scouring for iron ore and coal, set within a larger landscape of mineral working. The site is grouped with the scheduled monuments of Blaenavon Ironworks, Pwll du Quarry and Garnddyrys Forge. This was an area of iron ore extraction from at least the 17th century. Ore was dug from outcrops either side of the hilltop, and water employed to scour soil and clean dug ore. Extraction grew for Blaenavon Ironworks after 1788, but the area was largely worked out by the early to mid-19th century. One of the main scours (SO 2623 1060 to SO 2560 1010) was in its present form before 1812, and Pen-ffordd-goch or 'Forge' Pond (PRN 3355g, SO 2550 1086) shows scouring around SO 2570 1070 was completed before c1817. Many levels were established by 1812, allocated in patches to named miners. Early and well preserved features include leats, ponds, hushing dams, scours, deposition areas, tips, shaft mounds, levels, boundaries, tracks, and tramroad formations. A subsidence feature clearly illustrates pillar and stall workings near SO 2579 1072. Good hushes and leats survive around SO 2555 1010. Further leats are bisected by a stockpile tip extent by 1812 for limestone at SO 2544 1018. A weighing machine existed near SO 2548 1048.
