They are clustered in two pairs, separated from each other by roughly twelve metres, and positioned just below the last modern field boundary, midway between the island features known as Cruppaunroe and Canroe. One of the southern depressions is particularly indistinct, barely legible as a deliberate form, its interior quietly filling over time with beach stones. These are classified as enclosures, a broad archaeological term covering any deliberately bounded space, though the shallowness of these examples leaves their original purpose open to interpretation.

Beginish Island sits in the mouth of the Valentia River on the Iveragh Peninsula, a stretch of coastline with a long and layered human presence. The survey work of A. O'Sullivan and J. Sheehan, published by Cork University Press in 1996 as part of their comprehensive study of the Iveragh Peninsula, brought these features into the formal archaeological record. The two northern depressions are spaced 2.4 metres apart; the southern pair are set 6 metres from one another. Whether they represent the collapsed remains of small structures, storage features, or something else entirely is not established. Their circularity and their position relative to the field boundary suggest a purposeful arrangement, but the site offers more questions than answers.
