Description and History of Site:-
Workings on Nab Hill extend for over 1km north-south divided into a series of discrete delphs which were worked under different partnerships or ownerships. All worked flagstones and Fly Flats Sandstone in the Rough Rock Flags beds. From north to south they are Nab Hill Delphs, Woodcock Delph, Fly Delph, Far New Fly Delph, Nab Hill Quarry and Old Fly Delph. Woodcock also had several levels and shafts to access deeper and less weathered flagstone. Nab Hill Delphs have surviving infrastructure - dressing sheds, dressing floors, cabins, judd walls and trackways including an east-west stone-built causeway now used as a public footpath. Such was the scale of work here that there was a row of quarrymen's cottages and a public house, the Delvers' Arms, at SE0342 3195, all long since demolished. Nab Water Lane was the route by which stone products - mainly flagstone and roofing stone - was dispatched northwards, and southwards over Cold Edge. The first known date is 1841 when 14 men were employed here and maps of 1851 and c. 1880 show the workings.
