Fan Camp is a prehistoric hillfort located in Wales, situated on bedrock of Ashgill rocks comprising mudstone, siltstone and sandstone. The monument is protected by Cadw under reference CM170. The underlying geology of these sedimentary rocks, formed during the Ashgill period, provided the natural foundation for the site's construction and would have influenced both the hillfort's defensive positioning and the practicality of fortification work.
Hillforts of this type typically date to the Iron Age, though some may have origins in the Late Bronze Age. They served as defended settlements, storage centres or gathering places for the communities who built them. The choice of location at Fan Camp reflects the strategic importance of the site's topography, offering natural advantages for defence and visibility across the surrounding landscape. The mudstone and siltstone bedrock characteristic of the Ashgill formation would have provided adequate conditions for the erection of ramparts and ditches.
Today, the monument survives as a visible earthwork representing an important phase of prehistoric Welsh settlement. As a protected site under Cadw's stewardship, Fan Camp contributes to our understanding of Iron Age communities in Wales and the ways in which they organised their settlements and defences across the landscape.
