Great Haigh Sough
The Great Haigh Sough is a tunnel or adit driven under Sir Roger Bradshaigh's estate between 1653 and 1670, to drain his coal and cannel pits in Haigh on the Lancashire Coalfield. The sough's portal and two metres of tunnel from where it discharges water into the Yellow Brook at Bottling Wood is a scheduled monument.
==History==
Cannel had been dug from bell pits on Bradshaigh's estate since the 14th century where the seam was very close to the surface near the Old School Cottages. The sough was driven to drain the pits, which produced both coal and cannel and extended the life of their shallow workings, which were prone to flooding. The sough, a major investment was considered preferable to winding water from the workings by the primitive methods available at the time. Bradshaigh recorded a detailed survey of the construction of the sough and its shafts with instructions for maintenance so that, "the benefit of my 16 years labour, charge and patience (which it pleased God to crown with success for me and my posterity) may not be lost by neglect."
