Thundercliffe Grange was built in 1776 as a home for the Earl of Effingham. It has subsequently been used as an asylum and children's hospital/ home. Since 1980, it has been reused as private co-operative housing being converted into a number of flats. The Earl demolished the earlier grange buildings to build the new residence. The estate was sold into private ownership at the dissolution of the monasteries. The earlier hall was situated to the north and west of the current hall. Prior to the dissolution, the monks had established an ironworks in the vicinity by 1161 (Munford 2000,48). Excavations have left the foundations of some earlier buildings revealed making legibility of the former use fragmentary.
