On the 1926 revision of the Ordnance Survey six-inch map, it appeared as a hachured feature, the small radiating lines that cartographers used to indicate a depression or slope, suggesting something worth noting but giving no clear indication of what. It was not until an inspection in 1984 that the feature was identified for what it almost certainly is: a disused gravel pit, most likely dug sometime during the nineteenth or early twentieth century.

Gravel pits of this kind were commonplace across rural Ireland during that period, dug to supply material for road surfacing, drainage works, or estate construction. They were functional rather than monumental, which is precisely why so few were formally recorded. This one sits within what was evidently a managed landscape, parkland suggesting proximity to a larger estate, surrounded now by forestry. The hollow that marks it is modest, defined more by absence than by any visible structure. What makes it worth a second look is less the pit itself than the small puzzle it presented: a mark on a map that nobody had satisfactorily explained for nearly sixty years.
