The imposing ruins of Peveril Castle stand high above the pretty village of Castleton in the heart of Derbyshire’s Peak District.Mentioned in the Domesday survey, Peveril Castle is one of England’s earliest Norman fortresses. The castle was built sometime between 1066 and 1086. It was named after William Peveril, who was given the title of bailiff of the Royal Manors of the Peak after the Norman Conquest of 1066. Some historians believe Peveril was the illegitimate son of William the Conqueror. The keep was built by Henry II in 1176.A climb to the castle at the top of the hill to enjoy the breathtaking views over the Hope Valley is a highlight of a family day out in Castleton. Explore the remains of the keep including the garderobe (medieval lavatory!). Displays in the visitor centre tell the story of Peveril as the administrative focus of the Royal Forest of the Peak, a royal hunting preserve since the 11th century.The castle fell into disuse after Tudor times, and by the 17th century only the keep was in use - as a courthouse. When this was abandoned the castle gradually became ruined until what remained was restored this century.Inside the courtyard it is possible to trace the foundations of a hall, kitchens and other buildings, but it is the view across the surrounding countryside, encompassing Castleton and Cavedale, which is the real highlight. The castle is now in the care of English Heritage.Peveril Castle is reopens on 1st August, 3 days per week (Fri-Sun). Pre-booking essential.
