William Jones Varley, FSA (1904–1976) was a British geographer and archaeologist, particularly known for his excavations of English Iron Age hillforts, including Maiden Castle and Eddisbury hillfort in Cheshire, Old Oswestry hillfort in Shropshire, and Castle Hill in West Yorkshire. He was also a pioneer of geographical research and education in colonial Ghana where he worked from 1947 to 1956, and was involved in historical conservation there.

Eddisbury hill fort, also known as Castle Ditch, is an Iron Age hill fort near Delamere, Cheshire, in northern England. Hill forts are fortified hill-top settlements constructed across Britain during the Iron Age. Eddisbury is the largest and most complex of the seven hill forts in the county of Cheshire. It was constructed before 200–100 BC and expanded in 1–50 AD. In the 1st century AD, the Romans slighted the site. It was reoccupied in the 6th–8th centuries AD, and an Anglo-Saxon burh was probably established at Eddisbury in 914. In the medieval and post-medieval periods quarrying and farming have damaged the site. Ownership is currently split between the Forestry Commission and a local farm. Eddisbury is protected as a Scheduled Ancient Monument.
