 By the Domesday Book of 1086, Peveril had become a powerful landowner, with holdings in Nottinghamshire and Derbyshire.The exact year he founded the castle is uncertain, although it must have been started by 1086 as it is recorded in the Domesday Book, one of 48 castles mentioned in the survey and the only one in Derbyshire.The castle was recorded as standing at "Pechesers" which has been translated as both "Peak's Tail" and "Peak's Arse".
