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.
