Carl Wark

Carl Wark (sometimes Carl's Wark) is a rocky promontory on Hathersage Moor in the Peak District National Park, just inside the boundary of Sheffield, England. The promontory is faced by vertical cliffs on all but one side, which is protected by a prehistoric embankment. The cliffs and embankment form an enclosure that has been interpreted as an Iron Age hill fort, though the date of construction and purpose of the fortifications remains unknown. The site is a scheduled monument.

Carl Wark is located at grid reference SK259814, at an elevation of about 370 metres (1,214 ft) above sea level.Hathersage is about 3 kilometres (1.86 mi) to the west; Sheffield City Centre about 11 kilometres (6.8 mi) to the north-east. Historically this was within the ancient county of Derbyshire, but the surrounding area was annexed to the City of Sheffield in 1933, and now lies in the ceremonial county of South Yorkshire.

The promontory is a Millstone Grit outcrop situated in Hathersage Moor. From the north it is overlooked by the higher 434 metres (1,424 ft) peak of Higger Tor. To the east is the valley of the Burbage Brook, which is overlooked by Burbage Edge, a Millstone Grit escarpment. The land gently slopes away to the south following the course of Burbage Brook into the valley of the River Derwent. To the south-west, the land rises towards Winyards Nick and Over Owler Tor.
