Castell Olwen is a prehistoric hillfort situated in Ceredigion, Wales, designated as a Scheduled Ancient Monument (SAM CD161). The site dates to the Iron Age and comprises a substantial earthwork defence consisting of multiple banks and ditches that would have enclosed and protected a settlement on elevated terrain. The monument represents the typical defensive architecture of its period, when such fortified hilltop positions served strategic and communal functions across Wales and the broader British landscape. The physical remains visible today reflect the substantial effort invested in its construction and maintenance during the Iron Age period.
