The eastern part of the hill fort remained in use for at least the first few decades of the Roman occupation, although the duration and nature of habitation is uncertain. Many 1st-century Roman artefacts have been discovered near the east entrance and in the centre of the hill fort. It has been suggested that Maiden Castle was occupied as a Roman military outpost or fort and the settlement discontinued, as there is no known fort in the area and it was not uncommon for hill forts in the southwest to have been occupied by Roman forces. This was a characteristic of Vespasian's campaign in the region; there was military occupation at Cadbury Castle in Somerset, Hembury in Devon, and Hodd Hill in Dorset.
