The restraint of it is part of what makes it worth attention: no inscription, no heraldry, no effigy, just the clean geometry of a cross outline pressed into stone.

The slab sits in the west centre of the nave of Dunboyke church, positioned at a slight break in the southwest-facing slope of the ground. It measures just over a metre in height and three-quarters of a metre wide, with the cross itself occupying a roughly square area of sixty centimetres on each side across the slab's east face. Grave slabs of this type, a flat stone laid horizontally or set upright to mark a burial, were common across medieval Ireland, and the incised latin cross, with its elongated lower arm, was among the most enduring decorative choices available to the craftsmen who produced them. What survives here is modest in scale but carefully made, the groove work precise despite its shallowness.
