At Rodeen in West Cork, a rectangular slab of stone rises 1.8 metres out of the earth, oriented precisely along a north-south axis, its narrow face measuring around 35 centimetres and its broader face 80 centimetres. It stands in a burial ground, which means that whatever original purpose it served, it has long since been absorbed into a later layer of commemoration.

The stone was recorded by O'Brien in 1970 and subsequently catalogued in the Archaeological Inventory of County Cork. Standing stones of this kind are among the most enigmatic monuments in the Irish countryside. They date, in most cases, to the Bronze Age, though pinning a precise period to any individual example without excavation is difficult. Their alignments, particularly north-south or towards solar and lunar events, have led researchers to associate them variously with territorial markers, ritual sites, and astronomical observation points. The rectangular cross-section at Rodeen, rather than a roughly rounded or irregular profile, suggests some degree of deliberate shaping, though the stone's origins and the people who raised it remain unknown.
