When Britain’s appetite for coal increased during the Industrial Revolution, villages such as New Hartley sprung up around the pits that were sunk to mine the coal-rich seams that lay beneath. People living in this area of Northumberland had been mining coal long before the Hester Pit was sunk in 1845, but previous to this time, only the poor quality coal that lay close to the surface had been taken. The sinking of the Hester Pit marked the beginning of large-scale excavations on this spot, and the village of New Hartley grew up around it.
