English: Footpath through former Three Nuns Colliery, Hartshead, Yorkshire. This field was a coal mine, with shafts, spoil heaps and a mineral railway that was part of a network stretching from Brighouse to Low Moor (Bradford).The actual mine was dug about 100 yards behind the present Three Nuns pub. The mine was on land owned by the Armitage estate. The mine offices were in a courtyard entered under an imposing arched gatewaywhose three curved stones had 'Three Nuns Colliery' chiselled in them. Those stones had been retained when the colliery was demolished and 60 years ago still lay in the ditch behind the pub. They may still be there and could be searched for with geophyiscal radar. The mine buildings had all been demolished and the shaft capped with a great slab of concrete I used to walk on when visiting relatives over the fields. The railway was actually a horse drawn railway across the flat field shown and the at the hillside in the distance and just above the Grey Ox pub the horse was switched for a rope from a steam engine. At the hill top a horse was again used to drag the 'corves' across the flat lands to the hills of Low Moor where another steam engine lowered the 'corves' of coal to the Low Moor Ironworks the great engine wheel of which is still on display at Low Moor on the road to Wyke. Low Moor Ironworks made both cast iron castings including cannon but also rolled 'wrought' iron in a rolling mill using which the great wheel.
