The tumulus, a burial mound of the kind raised over the dead during the Bronze Age or earlier, was destroyed around 1926. Beneath it lay a cist, a small stone-lined box grave of the type typically used for individual burials in prehistoric Ireland, often containing skeletal remains or cremated bone along with personal objects. Both are gone now, the mound levelled and the cist presumably disturbed, leaving the landscape with no visible trace of what stood there.

The destruction was recorded, if not prevented. A reference in the Journal of the Royal Society of Antiquaries of Ireland from 1935 noted the site, nine years after the mound had already been lost. That gap between the event and its documentation is telling: rural archaeological sites across Ireland were regularly cleared, quarried, or ploughed out during the early twentieth century, often before anyone thought to record them in detail. The Stuckeen tumulus is one of a considerable number of such losses in the Ballinrobe district, which encompasses the landscapes around Lough Mask and Lough Carra.
