NEHL - A modest pit working named Thornley Pit stood east of Tow Law, linked to the Stockton & Darlington through Tow Law. There was a small shaft and a few small auxiliary buildings at the site, alongside some small coke ovens. It was linked to the village via a footpath leading south west to the Towlaw Hotel. There was also a Thornley Pit House, a public house standing on the main lane east.
