It is a ditch barrow, a form of prehistoric funerary monument defined not by a raised mound but by a shallow encircling ditch, known in archaeological terminology as a fosse, cut into the ground around a flat central area. The overall effect is subtle: the monument measures just six metres in diameter, with the fosse running to a width of roughly 2.3 metres at its broadest and dropping only about ten centimetres at its deepest point, dimensions that speak more to symbolic demarcation than to any dramatic earthmoving ambition.

What makes the Moanmore example particularly interesting is that it does not stand alone. A second ditch barrow of the same type lies just ten metres to the north-north-west, suggesting that this patch of Tipperary pasture was once a deliberately chosen place, perhaps a small funerary complex or a cluster of burials within a defined ritual landscape. The interior of this barrow is level and free of overgrowth, which makes its outline legible on aerial photography, the means by which its dimensions and character were first properly recorded. The south-east to south-west arc of the fosse's inner edge has been eroded over time, the kind of gradual attrition that wet, grazed pasture tends to produce across centuries of agricultural use.
