It is a Latin cross, meaning the lower vertical arm is longer than the other three, and it is plain throughout, with no ornamental carving to date it or assign it to a particular hand. What sets it apart is less what it has than what it lacks: that absent arm gives it an asymmetry that catches the eye once you know to look.

The cross sits south of the foundations of a church, recorded separately in the national monuments register. The church remains are designated DU021-034002, the cross DU021-034003, the two features catalogued as distinct but obviously related elements of the same ecclesiastical site. The cross itself is modest in scale, standing 0.7 metres high with a width of 0.7 metres and a thickness of 0.15 metres, dimensions suggesting it was never a towering processional monument but something more intimate, perhaps a grave marker, perhaps a devotional object placed within or near the church precinct. The record was compiled by Geraldine Stout and revised by Caimin O'Brien, with the most recent update logged in March 2023.

Saggart is a small village on the southwestern edge of County Dublin, within relatively easy reach of the city. The graveyard is the kind of place that rewards a slow circuit rather than a quick glance: the cross sits centrally, so it is not hidden, but the surrounding grave slabs and the low remnant walls of the church foundations give the whole enclosure a layered quality that takes a moment to read. The missing arm has not been recorded as lying nearby, so it is likely long gone, broken off at some point in the past and not preserved. Visitors with an interest in early ecclesiastical sites will find the combination of cross and church foundations worth considering together, even if neither survives in complete form.
