That is not an unusual story in itself, but the mound's own identity was never quite settled before it disappeared, and that ambiguity is part of what makes it worth noting.

The feature appears on the 1916 Ordnance Survey edition as a small circular hachured feature, meaning it was rendered with short radiating lines to suggest a raised form, and was given the name 'Corheen'. It was absent entirely from the earlier 1837 six-inch map. When inspected in 1988, it measured approximately 17 metres east to west and 13 metres north to south, low-lying and flat-topped rather than domed. That profile led field investigators to suggest it was more plausibly a platform, a levelled or built-up base intended to support a house or structure, than a burial mound of the kind more commonly recorded in the region. The proximity to Disert Bibar, the ecclesiastical enclosure just to the south-east, is suggestive. A disert, in early Irish usage, referred to a place of religious retreat or hermitage, and structures associated with such sites sometimes included ancillary buildings set at a slight remove. Whether the Corheen platform had any connection to that religious landscape remains unknown. By the time its significance might have been properly assessed, it had already been built over.
