Hillforts in Britain are known from the Bronze Age, but the great period of hillfort construction was during the Iron Age, between 700 BC and the Roman conquest of Britain in 43 AD. The Romans occupied some forts, such as the military garrison at Hod Hill, and the temple at Brean Down, but others were destroyed and abandoned. Partially articulated remains of between 28 and 40 men, women and children at Cadbury Castle were thought by the excavator to implicate the Cadbury population in a revolt in the 70s AD (roughly contemporary with that of Boudicca in the East of England), although this has been questioned by subsequent researchers. However, the presence of barracks on the hilltop in the decades following the conquest suggest an ongoing struggle to suppress local dissent.
