Heritage Open Day: A Holme Valley Civic Society presentation by Lawrence Baylin about the fascinating story of stone production for the Valley and beyond. Magnum village housed 60 quarrymen and their families with pubs, shops, a church and even a jail. Through the 19th Century, the industrial revolution created a need for stone - for the factories, for the railway platforms, for the streets and houses of the expanding towns. What had been small-scale quarries meeting mostly local need, became much larger operations and also grew in number and with a greater spread of customers, reached by the expanding network of railways. Magnum Bonum Quarry was opened in 1830, extracting sandstone of exceptional quality from the moors above Hade Edge, Holmfirth, to use for flagstones and walling.
