The 46 scheduled monuments include burial cairns from the Bronze Age, an Iron Age hillfort, and Roman camps. The medieval sites include two castles and a further four mottes as well as dwellings, crosses and churches. Finally the post-medieval sites include the blast furnaces and ironworks of the industrial period.
