It is recumbent, meaning it lies horizontally rather than standing upright, and measures roughly 1.55 metres in length by just over 0.62 metres wide. What makes it worth pausing over is the large latin cross cut into its upper face: nearly 0.8 metres tall and 0.5 metres across, scratched into the stone in two broad incised lines, each about a tenth of a metre wide. The workmanship is deliberately crude, without any of the refined ornament associated with high medieval stone carving, which gives it an austere, almost functional quality.

A latin cross, with its longer vertical shaft and shorter horizontal arms, is among the oldest and most widely used forms in Christian iconography, and incised examples like this one appear across early medieval Ireland on grave slabs, boundary markers, and church enclosure stones. The simplicity of the cutting here, two lines scratched rather than carved in relief, suggests it may belong to an early tradition, though without additional dating evidence it is difficult to be precise. The stone sits outside the nave wall of the Hook parish church, a location that hints it may once have served as a grave marker or a devotional stone associated with the site, later displaced or repositioned as the church itself was modified over the centuries.
