What is recorded here

No visible ruin remains in Béal Deirg Mór, though the land may still cover the tomb. The vanished court tomb belongs to the ancient megalithic tradition of County Mayo, marking a place where people once shaped massive stone before memory failed. Forgetting has not erased the action; it has only removed the warning that the ground was not empty.

Court tomb, dating to the Neolithic period (c. 3500–2500 BCE). These tombs are significant as early communal burial sites and reflect complex social organisation in prehistoric Ireland.
