The stone rises to 2.2 metres, measures 1.4 metres across and 0.34 metres deep at its base, and tapers to a rounded top, oriented on a north-north-east to south-south-west axis with a slight lean towards the west. Standing stones of this kind are prehistoric monuments, most commonly associated with the Bronze Age in Ireland, though their precise purposes remain debated: they may mark boundaries, burial sites, astronomical alignments, or routes through the landscape.

The stone was recorded as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published in 1986 under the editorship of J. Cuppage. That survey, produced through Oidhreacht Chorca Dhuibhne in Ballyferriter, remains a key reference for the remarkable concentration of prehistoric and early medieval monuments found across this peninsula. Gleann na nGealt itself, the valley in which this stone stands, carries a name that translates roughly from the Irish as the glen of the mad or the glen of the lunatics, a reference to a longstanding tradition that people suffering from mental distress were drawn to the valley, or were brought there, in the belief that its waters and surroundings held curative properties. The standing stone predates that folklore by millennia, but the two things share the same quiet ground.
