This is a barrow, a type of prehistoric funerary monument, and what makes this particular example quietly arresting is how intact its basic geometry remains: a flat central area, a low flat-topped bank running around it, and beyond that a fosse, which is a shallow encircling ditch, the whole structure measuring roughly 37.5 metres north to south and 33.5 metres east to west. The bog that closes in around it has, paradoxically, helped preserve it, the waterlogged ground discouraging the kind of agricultural disturbance that has erased so many comparable sites elsewhere in the country.

The fosse shows signs of having been recut at some point, possibly to improve drainage of the surrounding land, which means the ditch we see today may not be entirely as it was originally cut. A gap roughly two metres wide on the southern side of the bank could be an original entrance, though the qualification is important: such features are easy to misread, and later interference or simple erosion can produce openings that resemble deliberate breaks. The site was noted by Knight around 1975, and was recorded in fair condition at that time. Oval barrows of this general type are associated broadly with prehistoric burial practice in Ireland, though the specific date and function of any individual example is rarely settled without excavation.
