Castell Caer Lleion is a prehistoric hillfort located in Conwy, North Wales, designated as a Scheduled Ancient Monument under the reference CN012. The site occupies a prominent hilltop position and represents an important example of Iron Age defensive settlement in the region, though occupation may have extended into earlier periods. The fort is defined by substantial earthwork defences comprising banks and ditches that enclose the summit, a characteristic feature of Welsh hillforts constructed to control territory and protect communities during the later prehistoric period. Its strategic location reflects the settlement patterns and defensive requirements of Iron Age communities in North Wales.
