It is a modest but genuinely ancient thing, roughly 1.3 metres tall with a rectangular cross section and a pointed top, oriented broadly east to west. The stream that once defined the character of this low valley still runs about twenty metres to the north, though it is the stone, not the water, that marks the older boundary here.

Standing stones are among the most widely distributed prehistoric monuments in Ireland, yet their purpose remains genuinely uncertain. Some are thought to be territorial markers, others may be associated with burial, ritual, or astronomical alignment, though in most individual cases the evidence for any one interpretation is thin. This example in Clongeen is no exception to that ambiguity. Archaeological testing carried out in its vicinity in 2001 produced no material finds, leaving the stone without any obvious contextual clues about its date or function. What is known is that a second standing stone sits roughly 160 metres to the north, which raises the quiet possibility that the two were part of some related arrangement, though nothing has been established to confirm it.

The stone's present setting is an odd one. Housing development in the area could easily have seen it removed or buried, but instead it was preserved in situ on a small green, a familiar Irish compromise between construction pressure and archaeological conscience. It is not the most dramatic monument in County Wexford, but there is something worth pausing over in the fact that a pointed slab, erected by people whose intentions we cannot now recover, has outlasted every other structure that ever stood in this particular valley.
