Camp 530m E of Tonmawr is a prehistoric enclosure situated on the coalfield landscape of South Wales. The monument occupies land underlain by the South Wales Upper Coal Measures Formation, a complex sequence of mudstone, siltstone and sandstone deposits laid down during the Westphalian period, interspersed with coal and ironstone seams that would become economically significant in later centuries. The site is protected by Cadw under reference GM090.
Prehistoric enclosures of this type typically date to the Bronze Age or Iron Age and served various functions including settlement, stock management, or ceremonial purposes. Their survival on the South Wales coalfield is noteworthy, as the intensive industrial development of the region from the eighteenth century onwards has destroyed or obscured many such monuments. This enclosure represents an important archaeological record of prehistoric land use in an area later transformed by mining and manufacturing.
The monument's location east of Tonmawr places it within a landscape that retains traces of its pre-industrial character despite surrounding industrial heritage. The enclosure's form and construction reflect the economic strategies and social organisation of Iron Age or Bronze Age communities inhabiting the upland margins of the South Wales valleys, before coal extraction reshaped both the physical and cultural landscape of the region.
