Opened in 1837 and operated by the Dowlais Iron Company until its closure in 1893, the Edgehill mine in the Forest of Dean yielded a total output of 958,000 tons of iron ore. Situated in the vicinity of Westbury Brook, the mine reached depths of 559 and 666 feet and extended over 2 miles, stretching from almost to the Wigpool Mine in the north to the St Annal’s Shaft in the south. Additionally, an older pit located 140 yards NNE of the existing pit at an elevation of 520 feet was sunk to 340 feet and connected to the main workings by drives. Edgehill is a more recent name for the Westbury Brook Mine.
