Peveril Castle
Peveril Castle in Castleton, Derbyshire, England (SK149826) stands on a hill overlooking the village with an impressive view across the Hope Valley and Cave Dale. The castle is named after William Peveril, an illegitimate son of William I, who was granted Royal Manors of the Peak, shortly after the Norman Conquest in 1066 and thus administered the Royal Forest of the Peak on behalf of the king.
The castle consited of small square keep, which is still standing, and curtain walls. Traces of other buildings are visible within the walls, including the site of hall that would have been the main accommodation.
Peveril's son, another William, fell in to disfavour with Henry I, and in 1155 the King confiscated the Peveril estates. The castle has belonged to the Crown or the Duchy of Lancaster since, and is now in the care of English Heritage.
