The slab is not where it was found, nor where it was made. It currently sits in an Office of Public Works depot in Athenry, Co. Galway, having spent most of its known existence on Inchcleraun island in Co. Longford, beside the early Christian site known as the Woman's Church.

When the antiquarian F. J. Bigger recorded the stone in 1900, it was still on Inchcleraun, and he described it as a piece of sandstone grit approximately 26 inches by 21 inches, carved with a Celtic interlaced cross and bearing traces of an Irish inscription. Later examination revealed the full decorative scheme: a triple-lined incised double Latin cross, with a central circle enclosing a geometric pattern, and expanded D-shaped terminals that also carry geometric ornament. Running in parallel lines on either side of the cross shaft are two inscriptions. H. S. Crawford recorded one of these in 1913, identifying it as half uncial script, a form of rounded early medieval lettering used widely in Irish ecclesiastical contexts, and read it as "OR[OIT] DO LAITHB[ER]TACH", meaning "A Prayer for Laithb[er]tach". By Crawford's time parts were already fading; the inscription is now too worn to read directly. The second inscription has fared even worse, yielding only the letters B, an illegible character, A, C, and H.

The stone's displacement from its island site to a county Galway depot means it is not straightforwardly accessible to visitors. Inchcleraun itself, in Lough Ree, contains the remains of a significant early monastic complex, and the Woman's Church beside which the slab originally stood is among several early structures there. The cross-slab belongs to that place in origin, even if it no longer rests within it.
