A Tau Cross takes its name from the Greek letter T, its horizontal bar sitting flush with the top rather than crossing a vertical shaft, and examples from medieval Ireland are rare enough to attract serious attention. This one was moved from its original setting at Kilnaboy and is now the centrepiece of what the church has become, an interpretative centre dealing with the surrounding landscape and its history.

The church itself has a layered past. It was built between 1715 and 1720 by a woman named Cathleen Keightley, an unusual attribution for the period, when church-building was more commonly recorded under male patronage. It sat largely as built until the early nineteenth century, when a grant from the Board of First Fruits, an ecclesiastical body that distributed funds for the construction and repair of Church of Ireland buildings, paid for a steeple and vestry to be added. The restoration gave the building the form it holds today. A rectangular graveyard still surrounds it on level ground, and the whole arrangement in the village is quietly domestic in scale, nothing like the elevated or remote settings that Clare's older ecclesiastical sites tend to occupy.
