It sits about 80 metres from the shoreline on a machair plain, the kind of flat, grass-covered coastal grassland common to the Atlantic fringes of Ireland and Scotland. Two carved cross-slabs once marked its edges, upright stones protruded from the sand in its northern half, and the whole thing looked, when first properly recorded in the late 1930s, like a place that had been used for a very long time and in ways that left no clean narrative behind. One of those cross-slabs still stands on the eastern perimeter. The other is now in the National Museum of Ireland. The outline of the platform itself has almost vanished at ground level.

The scholar Françoise Henry visited and partly excavated the site in 1938, opening trenches across its central east-west axis and around both cross-slabs. What she found was not straightforwardly ecclesiastical, nor straightforwardly domestic. At the base of the eastern cross-slab, bones appeared 'in great abundance', though with no surrounding structures. On the western side of the platform, a hearth layer roughly 16.5 metres wide contained shells, burnt earth and stone, many animal bones, and the jaw and teeth of a wild boar. Two parallel lines of stones, set 4.5 metres apart, ran through the interior, one of them curving sharply eastward toward the southern cross-slab. Around the base of that slab, a semicircular bank of loose stones and black earth enclosed a deposit of ash, shells, and broken bones nearly half a metre deep. Among the animal remains in that deposit were cattle, sheep, pig, fish, bird, a large cat, a hare, and two fragments of whale bone; at a lower level still, cut and shed deer antler. East of the slab ran what Henry called a 'burnt stone path', its scorched nature unexplained, its full extent never traced.

The cross-slabs carry decoration that places them somewhere in the sixth to ninth centuries, implying the platform had some religious significance at least initially. But Henry found no enclosing wall around the perimeter, no burials, no structures, and she never investigated the clusters of upright stones in the northern half at all. The parallel stone rows may have divided the space, marked a processional route, or served some purpose no longer readable. The dense bone and ash deposits around the cross-slabs read more like the residue of repeated communal activity than of quiet devotion, and whether that activity was a continuation of the site's original purpose or something that came later is genuinely unclear. It is a National Monument in state ownership, but what kind of monument, exactly, remains an open question.
