At 2.85 metres tall and measuring 1.1 metres by 0.7 metres at its base, it is a substantial presence in the landscape, the kind of megalith that would once have been visible from a considerable distance across open ground. Standing stones of this type are among the most common prehistoric monuments in Ireland, raised during the Bronze Age as boundary markers, route indicators, or focal points for ritual activity, though in most individual cases the original purpose remains genuinely uncertain.

What gives this particular stone a small extra layer of interest is its proximity to another monument nearby. Roughly 250 metres to the north-north-east stands a stone known as Gallán na Cille Brice, a name that translates roughly as the standing stone of Brice's church, suggesting some later association with an early Christian site. The two stones are catalogued separately, but their nearness invites the question of whether this was ever a wider ceremonial or territorial landscape. The Baile An Mhuilinn stone is oriented east to west, a detail that may or may not be significant; some researchers have noted possible solar alignments in standing stone pairs on the Dingle Peninsula, though firm conclusions remain elusive. The stone was recorded and described as part of the Corca Dhuibhne archaeological survey published by J. Cuppage in 1986, a systematic study of the extraordinarily dense concentration of prehistoric and early medieval monuments that characterises this part of west Kerry.
