Bwlch yr Avan Dyke is a prehistoric linear earthwork located in Wales, recorded as a scheduled ancient monument under Cadw reference GM246. The dyke represents a characteristic example of Iron Age or Late Bronze Age defensive or territorial boundary construction, periods during which such linear earthworks were commonly erected across the Welsh landscape. The monument survives as an upstanding bank and ditch feature, typical of prehistoric dyke systems that functioned to control movement and demarcate land holdings or community boundaries. Such structures hold significance for understanding settlement patterns, territorial organisation, and the relationship between communities during the later prehistoric period in Wales.
