It is modest in scale, roughly 50 centimetres in height, and broken at the shaft, yet it carries on both faces a carved cross-in-circle, a form in which the arms of a cross meet within a raised circular ring, a motif with deep roots in early Christian stone carving across Ireland.

The cross was recorded by the archaeologist Seán P. Ó Ríordáin in 1947, who noted it in relation to other ecclesiastical remains at the site. His description, published in that year, identifies the cross-in-circle in relief at the intersection of the arms, and a second cross-in-circle on the reverse, positioned near the broken end of the shaft. The association with the medieval parish church grounds the object firmly in the long history of Christian activity at Saggart, though the precise date of the cross itself is not pinned down in the record. Photographs taken by H. A. Wheeler in August 1978 provide a more recent visual record, complementing Ó Ríordáin's earlier plate documentation.

Saggart is accessible from the N81 south of Dublin city, and the graveyard sits close to the village centre. The cross lies near the foundations of the old parish church, so a visitor should look towards that area of the graveyard rather than among the more recent headstones. Because the cross is recumbent or low-lying, it can be easy to miss if approached without some foreknowledge of its location. The carving itself is worn, as one would expect of granite exposed to the Irish climate over centuries, so morning light or overcast conditions tend to bring the relief detail into better relief than harsh midday sun.
