Description: The hill known as Carl Wark lies close to Higgar Tor between Stanage and Burbage Edges. It rises high above Burbage Brook and is a fine natural defensive position. The site encloses an area of about 0.8 hectares (2 acres) and is defended naturally on most sides by steep slopes. The side that is not protected by nature has seen the addition of a high rampart, constructed from earth and faced with a wall of large gritstone boulders. It is very likely that the hill was fortified in the Iron Age at the same time as Mam Tor, which you can see from Higgar Tor, only a few hundred metres away, and a plaque alongside the hill records this, though it may have been used earlier in the neolithic period. However, archaeologists also now tend towards the view that the massive fortifications which can still be seen at the western entrance were probably constructed in the Romano-British period at the start of the Dark Ages, maybe about 500 AD.
