I only captured this small section of the ruins that sit high above the village of Castleton

Peveril Castle Castleton Derbyshire
William Peverel was a favourite of William the Conqueror. He was greatly honoured after the Norman Conquest, and received as his reward over a hundred manors in central England from the king. In 1086, the Domesday Book records William as holding the substantial number of 162 manors, forming collectively the Honour of Peverel, in Nottinghamshire and Derbyshire, including Nottingham Castle.[7] He also built Peveril Castle, Castleton, Derbyshire. William Peverel is amongst the people explicitly recorded in the Domesday Book as having built castles.
