The Frith

The Frith is a small univallate Iron Age hillfort located north of Silchester (Calleva Atrebatum) in Hampshire, England, dating to approximately 500–300 BC[1]. The fortified site features a single earthwork bank enclosing all sides except the south-east, reaching about 1.5 metres (5 ft) in height on its western edge[1]. A surrounding ditch runs parallel to the bank, though its preservation varies across different sections[1]. The hillfort occupies a partially wooded area to the north and north-west, with a public footpath crossing the site from east to west[1]. As a univallate enclosure, it represents a relatively simple single-bank defensive structure from the late Iron Age period[1].
