The enclosure at Cappagh measures approximately twenty metres across, and while that is not especially large, what makes it worth a second look is the company it keeps. A smaller enclosure is attached directly to its eastern side, and to the south there is evidence of a field system that appears to belong to a later period, suggesting that this corner of hillside was organised, worked, and perhaps reorganised by different people at different times.

Enclosures of this general type, defined by a low stone wall and broadly circular or subcircular in plan, appear throughout the Irish landscape and tend to be associated with early medieval settlement and farming, though dating any individual example without excavation is difficult. They may have served as farmsteads, as enclosures for livestock, or as both at once. The relationship between the main enclosure at Cappagh and the attached smaller one to the east is the kind of detail that raises questions without answering them neatly. Was the smaller space a pen, a garden plot, a later addition built against an already ancient wall? The possibly later field system to the south hints at continuing use of the land long after the enclosure itself was in active use, though what form that use took remains unclear. The site sits on a stepped slope rising towards Fahee North, the kind of sheltered, elevated ground that early farmers across Ireland repeatedly chose for similar reasons, decent drainage, some visibility, a break in the wind.
