HER Info (unless otherwise noted)
This is the site of the Moss Pit owned and operated by the Delaval family. It was dug or 'sunk' from 1792 to 1793; it might be thought that this was an unsuccessful bell pit as a nearby wagonway was not extended to this pit. There were many small pits - probably slightly bigger than bell pit mining - in this area. Coal mining probably took place in Medieval times though many pits were sunk to the rich coal layers called seams in the 1780s and 1790s in this area.
