In the north-west corner of a graveyard in Carbury, County Kildare, a low rectangular mound sits slightly apart from the rest, its outline just clear enough to suggest something deliberate. The ground rises a little, the surface is uneven, and a grass-covered bank traces three of its four sides. An illegible headstone stands somewhere in the interior, its inscription long since worn past reading. Nothing announces what this feature is, or was.

Measuring roughly 13.8 metres east to west and 10.5 metres wide, the raised area is thought to be the levelled remains of an early church. The surrounding bank, between 1.8 and 2.1 metres wide and half a metre high on the exterior, is the kind of feature that survives when walls collapse inward over centuries and vegetation slowly absorbs the rubble. The graveyard itself carries a name that hints at the same origin: Templedooath, from the Irish for 'Black Church'. Whether that name refers to the colour of the stone, the religious order associated with it, or something else entirely is not recorded, but the coincidence of the mound's location and the graveyard's name has led to the reasonable suggestion that the two are connected, that what remains underfoot is precisely the church the place was named for.
