A púca is a shapeshifting spirit from Irish folklore, associated with wild or liminal places, and whatever prompted someone to attach that name to this particular scatter of rubble has long since been forgotten. What remains is a cairn of collapsed stonework, the largely unreadable remains of what were probably three conjoined hut structures.

The site was recorded as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published in 1986 under the direction of J. Cuppage. That survey documented the extraordinary density of prehistoric and early medieval remains across the peninsula, a landscape where stone-built huts, promontory forts, ogham stones, and early Christian enclosures survive in unusual numbers, in part because the relative remoteness of the area limited later agricultural disturbance. The three structures at Púca na nAsal were likely circular or subcircular dry-stone huts of the kind found widely across the peninsula, though the degree of collapse makes their original form difficult to read with confidence.
