The rath at Baile An Bhogaigh was destroyed in 1984, which gives it the particular melancholy of a place known only through its last recorded description, a kind of archaeological ghost. What survives is the account of what was there: a roughly circular enclosure about 20 metres across, sitting on a south-east facing slope that looked down over a stream valley running south towards Aghnalack.

A univallate rath, meaning one enclosed by a single bank and ditch rather than multiple concentric ones, was the most common form of defended farmstead in early medieval Ireland, typically associated with the period between roughly the fifth and twelfth centuries. This one followed the familiar pattern closely. The fosse, the external ditch, reached 1.5 metres deep and 4 metres wide at its best-preserved point, though it faded entirely along the south-east sector. The bank rose to about 1.75 metres on its outer face, and in the north-west a partial stone facing was still visible beneath the earthwork. Inside, the only feature that remained legible was a north-south ridge running from the centre of the enclosure to the northern bank, flanked on each side by a shallow depression. Its purpose was not recorded. The entrance had likely been blocked at some point, possibly by one of four field walls that radiated outward from the site. The damage had begun before the final destruction: the removal of an east-west field boundary along the southern side had already disturbed part of the bank, suggesting the slow attrition of agricultural pressure that preceded the outright loss of 1984. J. Cuppage documented the site before it vanished, capturing it in the 1986 Dingle Peninsula archaeological survey, which remains the only detailed record of what stood here.
