Camp Pen-y-Gelli is a prehistoric enclosure revealed by aerial photography in Wales. The site is protected by Cadw, the Welsh heritage body responsible for the country's historic monuments and archaeological sites.
The enclosure sits on bedrock composed of Wenlock Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone formations dating to the Wenlock period of the Silurian era. This geology has shaped both the landscape and the practical conditions for settlement, with the mixed rock types creating variable drainage patterns typical of upland Welsh terrain.
Aerial photography has proven instrumental in identifying the monument's ditched or ramparted boundaries, a recognition method particularly effective for cropmarks and soil shadows that reveal subsurface features invisible from ground level. Such prehistoric enclosures served multiple functions in their period—from stock control and defensive purposes to ritual or ceremonial roles. The specific topography and geology of Pen-y-Gelli contributed to its choice as a settlement or gathering place in prehistoric times.
