Marked on the OS maps as 'Gallaun', this ogham stone is located on a natural terrace on the lower SW slopes of Geokaun hill, Valencia Island, from which commanding views may be had to S and W. A second ogham stone stands 400m to NE in Kildreenagh ecclesiastical site (KE078-009004-). Of irregular elevation, this large stone rises to a maximum height of 2.4m, measures .77m x .45m at base and is aligned NNW-SSE. It inclines somewhat to NE and carries the inscription along its SE angle. Macalister's revised reading (1945, 226-7) of this is:
. . . ]ERRLONNA MAQI R[U]T[E]N[I]
The very weathered and uneven surface of the stone detracts from the general clarity of the inscription. The first stroke of the L is unclear, as is the final stroke of the second N. The next character appears to be M rather than A. Only two notches of the first I are discernible, and the first stroke of the third R is incomplete. The first stroke of the T and the final E and I are doubtful.
