Parts of an iron wheel rim were found, together with early Iron Age pottery. Taken together, the finds indicate the presence of a prosperous agricultural community at Bigbury during the Iron Age. Late Iron Age finds include good quality wheel-turned Aylesford-Swarling pottery. In spite of extensive investigation, no Iron Age coins have been recovered from Bigbury Camp; this has led investigator W. Rodwell to conclude that it was not significant as a permanent settlement. Artefacts recovered from Bigbury Camp are on display at museums in Canterbury and Maidstone. The site had experienced a long period of occupation during the Iron Age before the arrival of the Romans. The hill fort appears to have been first occupied around 350 BC, although the ditch-and-rampart defences were not built until the 2nd century BC. It is likely that Bigbury Camp was the British fortress that was attacked by the Roman Seventh Legion in 54 BC. Julius Caesar described how the entrances to the fort were barricaded with felled trees. The site was abandoned around this time, perhaps as a result of Caesar's attack, and the focus of settlement was transferred eastwards to Canterbury, which appears to have been deliberately founded to replace it. Preliminary archaeological excavations took place in 1933, during which two large trenches were cut across the north side of the main rampart.
