Measuring roughly sixty centimetres tall and forty-four centimetres wide, it is not large, but its surface is densely worked. The central figure of Christ on the cross is accompanied by carved symbols of the Passion, the instruments associated with the crucifixion narrative, including a ladder, a hammer, and pincers. A narrow border runs around all four sides, giving the whole composition a contained, formal quality that sets it apart from the rougher votive stonework often found at such sites.

Holy wells in Ireland have been places of devotion for centuries, typically drawing together pre-Christian water veneration and later Catholic practice. The placement of this plaque on the outside of the well's enclosing wall, at the north-east, suggests it was intended to be seen by those approaching or circling the site as part of devotional rounds. According to the scholar J. Higgins, the piece dates from the late eighteenth or early nineteenth century, a period when carved stone religious imagery was still being produced for local use in the west of Ireland, often outside the formal channels of church patronage. The Passion symbols carved alongside Christ, objects directly linked to the mechanics of the crucifixion rather than to saintly figures or abstract emblems, give the plaque an unusual specificity, grounding the devotional image in a narrative rather than simply an icon.
