Carl Wark

Carl Wark is an Iron Age hillfort on Hathersage Moor in the Peak District, just inside Sheffield's boundary in South Yorkshire[1]. The rocky promontory is defended by vertical cliffs on three sides, with a prehistoric embankment protecting the fourth side[1]. The date of construction and purpose of the fortifications remain unknown, though it is typically assigned to the Iron Age period[1]. The site is a scheduled monument and lies near Higger Tor[1][2].
