They are not especially imposing in their current state, each measuring roughly 1.7 metres by 0.95 metres, but one detail sets them apart from countless other fallen prehistoric stones scattered across West Cork: one of the slabs bears a drill-hole on its upper surface, a small but deliberate mark whose original purpose remains unclear.

The pair are recorded in close association with a nearby stone row, a prehistoric monument type common in Munster, consisting of two or more standing stones arranged in a roughly linear formation. Such rows are generally attributed to the Bronze Age, though their precise function, ceremonial, astronomical, or otherwise, is still debated among archaeologists. The Eyeries stones are catalogued as a separate feature lying to the south-east of that row, and were noted by the archaeologist Seán Ó Nualláin in 1988 as part of his survey of stone rows in the region, a body of work that remains a key reference for this monument type in Ireland. The drill-hole is an unusual feature; it may indicate that the slab was worked or adapted at some point, though whether this happened in prehistory or later is not recorded.
