Walk across the field where it once stood and you would notice nothing unusual, no earthwork, no ridge, no hollow. Yet the evidence is there, written in the crop itself. In dry summers, the buried remains of a circular bank cause the vegetation above them to grow and colour differently from the surrounding soil, producing a ghostly ring that only becomes legible from the air.

Aerial photographs taken in July 1970 revealed this cropmark clearly, showing a roughly oval shape measuring approximately 28 metres north to south and 34 metres east to west. The site sits on a natural rise in gently rolling terrain, the kind of elevated position favoured by those who built enclosed settlements and ceremonial spaces across Ireland during the early medieval period and before. Such enclosures, typically formed by a circular earthen bank and sometimes a ditch, served a variety of purposes depending on their size and period, ranging from farming homesteads to ecclesiastical enclosures. The name Monksgrange carries its own suggestive weight, a grange being a farming outpost associated with a monastery, hinting at a long connection between this land and some now-vanished religious community. What is clear is that the enclosure was still substantial enough to be mapped in the 1904 to 1905 edition of the Ordnance Survey six-inch series, where it appears as a single-banked oval feature, before it was subsequently levelled, most likely by agricultural activity in the intervening decades.

The 1970 aerial photograph also shows two smaller circular cropmarks nearby, one roughly 70 metres to the northwest and another approximately 120 metres to the northeast, suggesting that this was not an isolated feature but part of a broader pattern of activity across the same stretch of ground. Clusters of this kind are not uncommon in Ireland, where successive generations often settled and worked close to places already marked as significant, though what relationship these smaller enclosures bear to the main site remains unknown.
