Built entirely without mortar, the walls are roughly two metres thick and stand to a height of 1.7 metres, enclosing an interior space of around four metres in diameter. That wall thickness relative to the interior is striking: more mass than room, built to last rather than to comfort.

This is a drystone hut site, a category of structure found across the uplands of the Dingle Peninsula, where loose stone was stacked with considerable skill to create shelters that have outlasted centuries of Atlantic weather. Drystone construction relies on the careful selection and placement of uncut stone, with no binding agent, so that the weight and interlocking of the material itself holds everything together. The technique is ancient and widespread, but on the Corca Dhuibhne peninsula it appears with particular frequency, often in remote locations associated with seasonal grazing, small-scale agriculture, or earlier forms of habitation whose precise dates remain difficult to establish. The site at Com An Bhúlaeraigh was recorded by J. Cuppage as part of the Dingle Peninsula Archaeological Survey, published in 1986, a detailed fieldwork project that catalogued hundreds of such features across this corner of County Kerry.

The location, a modest terrace carved into a steep mountain face, would have offered some shelter from prevailing winds while remaining well above the valley floor. Whether it served a herder spending summer months on the high ground, or belongs to an earlier and less easily categorised period of use, is not recorded. What the structure does offer, in its proportions alone, is a quiet sense of how much effort went into making even a temporary or seasonal place workable in a difficult landscape.
