Input: Question: Which era for which there is archcaelogical evidence of habitation was longest before the present day? Passage:There is archaeological evidence such as a blade implement and arrowheads to suggest habitation as early as the Mesolithic and Neolithic eras. The Bronze Age finds in the area have proved more numerous. They have included a set of ring ditches, a rapier and several spearheads. The village is also noteworthy as the site of a substantial Iron Age hillfort, alternatively known as a bertune, which would later be pronounced "Burton" in the Norman fashion (the name of the village until the early 14th-century). Excavated in 1950–1951, The discovery of Gaulish-made samian ware and a distinctive coin, along with coarse-gritted and medieval pottery, have led archaeologists to believe that the fort was occupied by Roman soldiers sometime after their invasion of Britain in 43 AD under Vespasian. Such was not uncommon in other hill forts of the Iron Age, with Maiden Castle and Hod Hill, both in the county of Dorset, later occupied by Romans as strategic military bases.
