Llanfilo Camp is a prehistoric hillfort located in Wales and scheduled under Cadw protection as monument BR040. The site occupies ground underlain by Lower Devonian rocks of undifferentiated character, comprising mudstone, siltstone and sandstone formations laid down during the Early Devonian period. This geology gives the hilltop a stable foundation of ancient sedimentary strata.
Hillforts of this type typically served multiple purposes across the Iron Age and earlier periods, functioning as defended settlements, administrative centres and places of refuge. Their hilltop positions provided natural defensive advantages, whilst the surrounding landscape allowed occupation communities to monitor territory and control trade routes. The topography of Llanfilo Camp would have exploited the local terrain for both practical and strategic benefit.
The monument remains an important record of prehistoric settlement patterns in Wales. Its scheduling recognises the archaeological value of the site's earthworks and the potential for buried deposits that hold evidence of Iron Age or earlier occupation, land use and the societies that constructed and inhabited such defended places across the Welsh landscape.
