It is a baptismal font, cylindrical in form and roughly 80 centimetres across, with a sub-rectangular basin cut steeply into its upper surface. The basin measures 48 centimetres by 45 centimetres at the top, narrowing slightly toward the base, and drops to a depth of 18 centimetres. What makes it quietly interesting is the drain hole worked through the stone at the basin's edge, angled at roughly 45 degrees. It opens at 4 centimetres within the basin, pinches to just 1 centimetre through the body of the stone, then widens again to 5 centimetres where it exits. That engineering detail, modest as it sounds, tells you something about the care taken in its original making: water blessed for baptism was not simply left to evaporate or be tipped out carelessly.

The font is believed to have come from Castletimon Church, a medieval ecclesiastical site in the same part of Wicklow. Fonts of this kind, carved from local stone and fitted with drainage to allow the removal of water after use, were standard furnishings in parish churches throughout the medieval period, though relatively few survive intact and in traceable context. This one has clearly travelled at some point from its original setting, which is itself a small story. The rim around the basin is roughly flat but damaged along one edge, and the base is uneven, falling slightly to the side where the drain hole sits, suggesting the stone was not cut to sit perfectly level or has worn unevenly over centuries of use and relocation.
