In a graveyard at Commons in County Kildare, among the remains of a ruined church and three carved cross slabs, there sits a fragment of a granite baptismal font in a notably poor state of preservation. Fonts of this kind were the vessels in which water was blessed and used for baptism, typically placed near the entrance of a church, and their presence at a site usually signals that a functioning parish church once stood there. That this one survives only as a fragment, in a field of the dead alongside a roofless ruin, gives the place a quietly layered character.

Three cross slabs were recorded at the site in 1985, flat or upright stones incised with a cross, a common form of early Christian grave marker found throughout Ireland. Together with the font fragment and the ruined church, they suggest a religious site of some age, though the surviving material is too worn and fragmentary to say much more with confidence. Granite is a durable stone, which makes the poor condition of the font all the more telling; whatever befell it was significant enough to reduce even that hard material to a remnant.
