It is broad and thick at the base, averaging around 1.25 metres in width and 1.15 metres in thickness, and its orientation runs roughly east-south-east to west-north-west. About 75 metres to the south, the land falls away gently towards the Meennascarty river. The stone sits in ordinary farmland, neither fenced off nor formally presented, the kind of thing you might pass without registering its age or purpose.

Standing stones are among the most common prehistoric monument types in Ireland, yet also among the least understood. They were erected across a very long span of time, most likely during the Bronze Age, and theories about their function range from territorial markers to ritual focal points to astronomical alignments. What is clear is that erecting a stone of this size required coordinated effort and that someone, at some point, considered this particular spot worth the trouble. The stone at Duagh was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a detailed catalogue of the prehistoric and early historic landscape of this part of Kerry, a region that preserves one of the densest concentrations of ancient monuments in western Europe.
