The circle survives intact, which is rarer than it sounds; only the northern entrance stone has fallen. The interior, rather than being left open, is filled with field stones, giving the impression that the space has been quietly tidied away over generations of agricultural use.

Five-stone circles are a type of stone circle found almost exclusively in counties Cork and Kerry, characterised by their modest scale and a consistent architectural logic: five upright stones, known as orthostats, arranged in a ring with a deliberate axial alignment. At Lettergorman, that axis runs northeast to southwest, a orientation shared by many similar monuments and thought by some researchers to relate to solar or lunar events on the horizon. The orthostats here range from 0.7 to 1.7 metres in length and reach between one and 1.4 metres in height, with the internal measurement along the main axis recorded at 2.7 metres. The site sits on the shoulder of a south-facing hill slope, north of the Glashagloragh river, a position that would have offered both visibility across the landscape and a degree of shelter. It is catalogued in the work of Seán Ó Nualláin, who documented Cork and Kerry stone circles extensively in the early 1980s.
