That combination, a sacred water source, an ancient tree, and a fragment of early Christian stonework stored informally within reach of both, points to the kind of layered, unsupervised veneration that often survived at rural sites long after any formal religious structure had disappeared.

The cross-head comes from Ogulla, Co. Roscommon, where it was associated with a holy well recorded under the Sites and Monuments Register reference RO022-106003. A high cross, in Irish ecclesiastical terms, is a freestanding stone cross, often elaborately carved, that served devotional, commemorative, or territorial functions at early medieval religious sites. What survives here is only the crux, the central crossing piece, measuring roughly 0.8 metres by 0.8 metres and about 0.3 metres thick. One face carries a large boss, a raised circular projection common in Insular stone carving, while the other is carved with a plainly rendered head. Peter Harbison, whose 1992 catalogue of Irish high crosses remains the standard reference, includes this fragment in the first volume of that work. The piece is catalogued under RO022-106005, compiled by Michael Moore and uploaded to the record in October 2013.

The cross-head itself is now held by the National Museum of Ireland, whose principal site is on Kildare Street in Dublin city centre, and it is there that any visitor hoping to examine the carving would need to go. The Ogulla well site in Roscommon retains its own interest for those travelling in that direction; holy wells in Ireland were typically associated with pattern days, local patron festivals held on a saint's feast day, and many such sites still carry traces of votive practice in the form of tied cloth or small offerings left near the water. At Ogulla, the large tree that once sheltered the cross-head would be worth noting as a landscape feature in its own right, since trees at holy wells were often considered as sacred as the water beneath them.
