Cefn-Du Camp is a prehistoric hillfort situated in Wales on bedrock composed of Wenlock Rocks, a mixed sequence of mudstone, siltstone and sandstone laid down in the Wenlock period. The geology of this site—relatively soft sedimentary strata—would have presented specific challenges and opportunities for the construction and defence of the fort. The site is protected as a scheduled monument under Cadw, the Welsh heritage organisation, under reference MG008.
Hillforts of this type typically date to the Iron Age, though some may have origins in the Bronze Age. Such fortifications were commonly built on elevated positions to exploit natural topography, and the choice of this particular location would have been influenced by both the underlying solid geology and the surrounding landscape. The Wenlock bedrock, being more readily worked than harder igneous stone, may have facilitated ditch-cutting and rampart construction.
Today, Cefn-Du Camp survives as an archaeological monument reflecting Iron Age settlement patterns and defensive strategies in Wales. Its protection by Cadw recognises its significance to understanding prehistoric Welsh communities and their relationship with the land they occupied.
