Overview

History & significance

Bwlch yr Avan Dyke is a prehistoric linear earthwork located in Wales and designated as a Scheduled Ancient Monument under the reference GM246. The monument takes the form of a substantial dyke that survives as an upstanding bank, representing the type of territorial or defensive boundary construction characteristic of later prehistoric periods in Britain. Its precise dating and original extent remain subjects of archaeological study, though such linear earthworks are typically associated with Bronze Age or Iron Age communities. The dyke's survival in the Welsh landscape provides evidence for patterns of land division and social organisation among prehistoric populations in the region.
