That a graveslab should end up as architectural salvage is unusual enough, but the carving on its surface makes the repurposing all the stranger. The slab, measuring 1.32 metres long and 0.48 metres wide, is decorated with two groups of concentric circles, each centred on a cup mark, along with a band running down the centre and a herringbone pattern. These are the kinds of motifs more commonly associated with prehistoric rock art than with early Christian burial, and their presence on a graveslab points to a long and complicated relationship between older decorative traditions and early medieval stone-cutting in Ireland.

The slab is one of two early graveslabs recorded from Ballyman, a site that retains the remains of a small church. Exactly when the slab was repositioned as a window lintel is not documented, but it was removed from that context in 1940, when it was transferred to the National Museum of Ireland in Dublin, where it is held under registration number 1940:106. The site at Ballyman has been noted in the archaeological literature by Ó hÉailidhe, writing in 1973, and by Swords in 2009, both of whom catalogued the slab as part of broader surveys of early medieval carved stonework in the region.

The slab itself is now held at the National Museum of Ireland, so any visitor hoping to see it should head to the museum's collections rather than to Ballyman. The museum, on Kildare Street in Dublin city centre, holds a substantial collection of early medieval material, and staff can advise on whether the slab is currently on display or accessible through the study collections. Those with an interest in the Ballyman church site itself, where the second graveslab and the church remains are recorded, should be aware that it is a rural site and worth checking access arrangements before travelling.
