Peveril Castle is an 11th century stone keep and bailey fortress, founded by William Peverel. Built on a strong natural site, the elegant square Norman keep, guards the gateway to a D-shaped outer bailey, sited across the Peak Cavern gorge. In the sloping triangular inner bailey are the foundations of a chapel and two halls, the northern curtain wall displays herringbone masonry and a shallow buttressed turret. The 12th century round-arched gatehouse is now the main entrance but originally was only the back gate to the castle. Part of village defenses can be seen from the wall by the turret. 2 miles east is Hope Castle and 6 miles east is Hathersage Castle.
