What makes the group quietly compelling is the arrangement: not one shelter but three, connected, graduated in size, and oriented along a west-to-east axis as though they grew outward from the largest over time.

The westernmost hut is the biggest of the three, roughly oval in plan and measuring about five metres across. Its walls survive to around 1.1 metres, though no original entrance can be made out. Attached to it is a middle hut, similarly subcircular, smaller at roughly 4.4 by 2.4 metres, and linked to the third by a communicating passage less than two thirds of a metre wide, just enough to move between them. The easternmost hut is the smallest, nearly circular, with walls still reaching 0.7 metres. The whole complex was recorded and published in A. O'Sullivan and J. Sheehan's archaeological survey of the Iveragh Peninsula, published by Cork University Press in 1996, which placed it among the many early settlement remains scattered across this part of South Kerry. Structures like these are generally associated with early medieval or earlier pastoral activity, temporary or seasonal habitation by people using the upland ground for grazing, though the specific date of this group has not been firmly established.

The site lies about 100 metres north-east of a related recorded monument nearby, and the Bunbinnia area contains other archaeological features in its wider landscape. The low walls blend readily into the terrain, and the communicating passage between the middle and eastern huts is the detail most worth looking for once you are among them.
