Cratcliff Rocks is an extensive rock outcrop on the edge of Harthill Moor in the eastern gritstone moors of Derbyshire. Cratcliff Rocks defended settlement is an ancient encosure in the field to the north east of Robin Hood's Stride. The monument lies on the western edge of the Cratcliff Rocks outcrop and is in the form of a round enclosure about 100m wide with a 5m wide ditch cut into the rock. Several building platforms have been identified inside the enclosure. Whilst the site has not been excavated, it is considered to be linked to the other Bronze Age features of Harthill Moor. Cratcliff Rocks hermitage is a medieval hermit's cave. The rock shelter has a number of recesses cut into the walls for candles and sacred objects. A bas-relief crucifix carved in the cave has been dated to the 13th or 14th century. On the rock face outside the shelter, chiselled grooves and sockets for timber beams indicate where the roof structure was of a building adjoining the cave.
