Known locally as Ulligadrevil, or in Irish Ulaidh an Draghbháil, the site takes the form of an ovate enclosure containing what appear to be the remains of hut sites and graves. That combination, a domestic or defensive outline gradually absorbed into funerary use, is what makes it particularly difficult to read from the surface alone.

The working interpretation is that the enclosure began its life as a ringfort, the circular or oval earthwork enclosures that dot the Irish countryside in their thousands and were typically used as defended farmsteads during the early medieval period. At some later point, it seems to have been repurposed as a cillín, or calluragh burial ground. A calluragh, sometimes also spelled cillín or killeen, was an informal burial ground used in Ireland for those who could not be interred in consecrated ground, most commonly unbaptised infants. These sites were often placed in locations already considered old or set apart, such as abandoned enclosures, ruined buildings, or the margins of bogs and fields. The reuse of an earlier earthwork for this purpose was not unusual; there was a logic to choosing ground already perceived as ancient and bounded. The 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, compiled by J. Cuppage, recorded the site and noted frankly that classification from surface inspection alone remains uncertain, a rare and welcome admission of ambiguity in such surveys.
