The main stone measures roughly 2.1 metres long and 1.7 metres wide, with a maximum height of about a metre. The arrangement has the character of a dolmen, the term used for a megalithic tomb in which a large capstone is supported by upright stones, though the classification here is deliberately cautious: it is recorded simply as a megalithic structure, leaving open the question of what it originally was or how much of its present form reflects deliberate prehistoric construction rather than later disturbance.

What makes the Freahanes site particularly interesting is the company it keeps. An upright stone, 1.7 metres tall, stands just 1.2 metres to the west, close against a field fence. And roughly 30 metres to the north-east there is a separate standing stone, a single dressed or undressed upright planted vertically in the ground, whose presence suggests this corner of a West Cork field was once a more deliberate ritual or ceremonial landscape. Clusters of this kind, where a possible tomb or platform stone sits in close proximity to standing stones, are known elsewhere in Cork and Kerry, though they are rarely well documented and the relationships between the individual elements are not always understood. The slight rise on which the main boulder rests, modest as it is, would have given the structure a degree of visibility across the slope, which is consistent with how prehistoric communities across Ireland chose locations for monuments intended to be seen.
