Craig-na-Altair, Mass Rock Road, Ballyholland Upper, Newry, Co Down

Craig-na-Altair is a mass rock of local interest, one of the few known examples in the Mourne Area. Dating to approximately 1800-1819, it is set into a rocky outcrop on the south side of Mass Rock Lane. The rock itself is a large, roughly rectangular structure raised on a cement-pointed granite rubble plinth and constructed of roughly dressed granite. A Celtic cross is engraved on its front face, with small circular Maltese crosses at each top corner.

The layout of the enclosure resembles that of a church, featuring a nave and three curvilinear rubble granite steps ascending to an apse-like area. The site is grassed and enclosed to the rear by the rocky outcrop. To either side of the mass rock, resting on the rocky outcrop, are single piece dressed granite holy water fonts, each with a round-headed niche, chamfered base, and an inscription stating '1954'.

A modern polished granite plaque to the right of the mass rock commemorates its erection in the Marian Year of 1988 and blessing by the Bishop of Dromore in June 1988. A granite cross stands to the rear left, on the rocky outcrop. The east face of the cross is inscribed with Gaelic text "CR 2113/ nah 2n OR21/ leizead aifreann Annseo/ nuair biod luas Ar ceann/ 3AC SA3 AIR ineirinn" and the base reads “E R. I.N.F Ballyholland Sept 8 1918”.

The site is bounded by a mesh wire fence with a modern wrought iron gate. The area has been landscaped as a tourist viewpoint, complete with a small car park opposite, and offers impressive views of the surrounding locality. While in use from the mid-1700s, it was not explicitly marked on the 1834 Ordnance Survey 6-inch map. The site is owned by the Roman Catholic Church and serves as both a mass rock and a monument.
