That is a remarkable amount of historical weight for an object measuring just 39 centimetres tall and 32 centimetres wide, with a neat square cross-section of about 10 centimetres on each side. On one face, an incised cross with expanded terminals, meaning the arms flare slightly outward at their tips, has been carefully cut into the stone. The cross itself is probably 18th century in date, though the church it once accompanied is considerably older.

Around 1900 the stone was moved from the site of St. Brecaun's church to the graveyard at Churchtown, where it was incorporated into a later memorial. The relocation was presumably intended to preserve it, though the effect was also to physically separate the object from the ecclesiastical site it originally marked. St. Brecaun, to whom the church was dedicated, is one of those quietly persistent figures of early Irish Christianity whose name survives in place and church dedications long after the details of his life have faded. The stone now sits embedded in its later memorial context at Churchtown, its original purpose as a graveyard marker for St. Brecaun's site effectively archived in granite.
