It is classified as an embanked barrow, a prehistoric funerary monument type in which a low bank or lip encloses a raised central platform, distinguishing it from a simple mound burial. What makes this example at Scregg quietly compelling is precisely its modesty: the whole structure spans just 7.5 metres north to south, the enclosing bank rises no more than 0.7 metres above the surrounding ground at its highest point, and the interior platform lifts only 0.3 metres above the bank's inner edge. The geometry is compact and well defined nonetheless, the kind of thing that rewards a slow, deliberate look rather than a passing glance.

The ridge on which it sits runs roughly northwest to southeast, with the ground falling away to the northeast, giving the site a natural elevation over the surrounding countryside that would have made it a conspicuous spot for anyone moving through this part of Mayo in prehistory. Barrows as a class span a broad swathe of time, appearing from the Neolithic period onward and remaining in use through the Bronze Age, and their placement on visible, elevated ground was rarely accidental. The platform at Scregg is grass-covered throughout, and hawthorn bushes have established themselves on the bank at the northeastern arc, softening the outline further. The bank itself varies slightly in width, measuring 2.3 metres on the northern side and 2 metres to the south, suggesting either differential settlement over the centuries or variation in the original construction.
