They are easy to walk past, easy to dismiss as natural variation in the terrain, and yet their arrangement is too deliberate to be accidental. Two sit close together in the north, roughly 2.4 metres apart; another pair lies 12 metres to the south, set about 6 metres from each other. Whatever made them, something organised them.

The most closely examined of the four, a depression in the north-east of the grouping, measures approximately 3.3 metres north to south and 3.2 metres east to west, with a flat-bottomed interior sitting just 24 centimetres below the surrounding ground level. Its eastern edge is defined by a low bank, around 65 centimetres wide and only 20 centimetres in external height, which suggests the deliberate shaping of the earth rather than simple subsidence or erosion. Features like this are sometimes classified as enclosures, a broad archaeological term for any defined area bounded by a bank, ditch, or wall, and which could have served purposes ranging from small-scale livestock management to ritual use. On Beginish, which sits off the south-west coast of Kerry near Valentia Island in the waters of the Iveragh peninsula, the function of these particular features remains uncertain. The island has a documented history of early medieval activity, which gives the depressions a plausible context, though the features themselves have not been definitively dated. The measurements and layout were recorded in A. O'Sullivan and J. Sheehan's archaeological survey of the Iveragh peninsula, published by Cork University Press in 1996, which remains the foundational reference for the region's field monuments.
