Unlike the large mounded cairns that draw visitors to more celebrated sites, a ring barrow is typically a low, circular earthen bank enclosing a central area, often the burial place of a single individual or a small number of cremated remains. They date generally to the Bronze Age, though some examples reach back into the Neolithic, and their modest profile means they are easily overlooked, blending into the surrounding landscape until you know what you are looking for.

Behy Beg lies in a part of Mayo that has long been associated with early settlement and prehistoric activity, a county whose boglands have preserved an extraordinary range of ancient remains. Ring barrows across Ireland are thought to have served both as burial monuments and as markers of territory or ancestral significance, visible reminders to those who lived nearby that this ground was claimed, remembered, and held in some form of reverence. The specific history of this particular example, including when it was constructed, by whom, and what if anything it contained, remains undocumented in any publicly available detail at present.

What can be said is that the monument exists, that it has been recorded, and that it occupies a spot in the Mayo landscape that was once considered significant enough to shape and mark with deliberate human effort. That act of marking, however faint it now appears, is itself a small fact worth sitting with.
