English: Site of Tindale spelter works A large works existed here during the 19th century to extract zinc from spent lead ore brought down from Alston Moor. The works closed in 1895 when Lady Carlisle, the landlord, insisted on high standards for workers' houses, which proved uneconomic for the operators to provide. The works were reopened briefly twice in the 20th century. In the 1950s, the huge quanitity of waste material was used as hardcore in the construction of the Blue Streak rocket testing facility at Spadeadam. Small quantites of slag can still be seen on the slopes.
