Danebury is an Iron Age hillfort in Hampshire, England, about 19 kilometres (12 mi) north-west of Winchester (grid reference SU323376). The site, covering 5 hectares (12 acres), was excavated by Barry Cunliffe in the 1970s. Danebury is considered a type-site for hill forts, and was important in developing the understanding of hillforts, as very few others have been so intensively excavated. Built in the 6th century BC, the fort was used for almost 500 years, during a period when the number of hill forts in Wessex greatly increased. Danebury was remodelled several times, making it more complex and resulting in it becoming a "developed" hill fort. It is a Scheduled Monument and a Local Nature Reserve called Danebury Hillfort. The Scheduled Monument is surrounded by a Site of Special Scientific Interest, designated as Danebury Hill. Source: Wikipedia (en)
