Castlenagree is a prehistoric mound located in Moyle, Northern Ireland, situated on bedrock of Palaeogene extrusive rocks comprising mafic lava and mafic tuff. The monument's precise classification—whether cashel (stone-built enclosure) or barrow (burial mound)—requires further investigation, though its mounded form suggests origins in the prehistoric period. The volcanic geology underlying the site is characteristic of the Palaeogene geological formation that dominates much of northern Antrim.
The mound occupies a landscape shaped by ancient lava flows and associated volcanic material. This geological setting would have influenced both the monument's construction and its survival over millennia. The exposed volcanic bedrock in the surrounding terrain provides evidence of the dramatic geological events that shaped this region tens of millions of years before human settlement.
Castlenagree is protected as a scheduled monument by the Historic Environment Division under reference 190, recognising its archaeological significance. The monument's survival and formal protection ensure that this enigmatic prehistoric structure remains available for future study and interpretation, contributing to understanding of early settlement and ritual practices in the Moyle region.
