Roughly oval in plan and measuring 37.5 metres north to south and 24.8 metres east to west, it is large enough to have housed a farmstead, and its position on high ground was almost certainly deliberate, offering both visibility and a degree of natural defence. What makes it quietly arresting is not what survives but what has half-disappeared: the earthworks are present on one arc of the circuit and then simply gone on the other.

This is a rath, the most common type of ringfort found across Ireland, typically consisting of a roughly circular area enclosed by one or more earthen banks with intervening ditches, known as fosses. They were built throughout the early medieval period, broadly from the fifth to the twelfth centuries, and served primarily as enclosed farmsteads for the farming families who dominated the rural landscape of Gaelic Ireland. At Crossconnell More, two banks and a fosse still define much of the perimeter, though all three are degraded. From the south-south-west around to the north-north-west, no surface trace of either the fosse or the outer bank remains at all, erased by centuries of agricultural use or natural erosion. A gap of 3.1 metres on the south-eastern side may represent the original entrance, a detail that, if accurate, would align with a broader pattern seen at comparable sites where entrances face the south or east.
