Notes: "Among the largest and most complex of Iron Age hillforts in Europe, Maiden Castle’s huge multiple ramparts once protected several hundred residents. Excavations in the 1930s and 1980s revealed the site's 4,000-year history, from a Neolithic causewayed enclosure to a small Roman temple built on the site in the fourth century AD. They also produced evidence of an extensive late Iron Age cemetery, where many of the burials had suffered horrific injuries in attacks or skirmishes." Source: English Heritage. (A nice timeline of the hill fort's development over the years can be found here).
"It is thought that the construction of Maiden Castle began around 3000 BC and flint tools and other objects dating from that time have been found," according to Historic UK. "The late Stone Age/ early Bronze Age people who lived there built a massive ditch and bank some 545 metres in length. There are Bronze Age burial mounds on the right hand end of the castle."
Roman conquest: The Maiden Castle hillfort was taken by the future Roman emperor Vespasian (founder of the Flavian dynasty) in the invasion of 43 AD. At the time, the fort was inhabited by a Celtic people -- the Durotriges tribe.
According to the Oxford Classical Dictionary (3rd ed. revised), the Durotriges "were a British tribe in Dorset and surrounding areas. They offered heavy resistance to the Roman advance by Legio II Augustus, commanded by Vespasian. These campaigns suggest a decentralized social organization during the Iron Age."
The Romans built a temple -- possibly to Minerva -- at the hillfort, which was later abandoned. It may have been occupied by the Saxons at some point, but it probably lay deserted for over a thousand years.
