The structure is a leacht cuimhne, a commemorative monument of a kind found across the Irish-speaking west, typically a mortared or dry-stone cairn erected at a significant spot to mark a death or keep a person's memory in place. This particular example, located in Eochaill, is a square mortared pier measuring 1.3 metres on each side and standing 2.4 metres tall, topped by a cross inscribed with the letters IHS, the traditional Christogram derived from the Greek name for Jesus.

What makes the structure quietly affecting is the span of its two plaques. The first, set into the south-western face, commemorates Bridget Dirrane, recorded also under the name O Brien, and is dated 1811. The second marks Julia Dirrane, dated 1868. Fifty-seven years separate the two inscriptions, yet they share the same stone, the same family name, the same form of memorial. Whether the monument was built in 1811 and returned to in 1868, or whether both plaques were added at a later point, the notes do not say. The double inscription suggests a family that maintained its attachment to this particular spot across generations, treating the leacht not as a one-time marker but as something closer to a continuing presence in the landscape. Tim Robinson, whose fieldwork underpins the record of this site from 1980, documented much of the human and physical geography of Connemara with exceptional care, and it is largely through his attention that small monuments of this kind entered the scholarly record at all.
