What remains is, in the most literal sense, invisible: a circular enclosure detectable only as a cropmark, the faint differential in vegetation that appears in dry summers when buried earthworks affect the growth of grass above them. The enclosure was first caught on aerial photography in July 1968, and its circular form points to origins in the early medieval period, when Irish monastic communities typically enclosed their churches and associated buildings within a roughly circular earthen or stone boundary.

The place had a name, at least. The historian William Carrigan, writing in 1905, recorded that a portion of the demesne was still known as the "Church field", and that locals could point to a slight rise in the ground where the church had stood. He identified it as Cill Feichín, the Church of St. Feichin, also recorded in Elizabethan documents as Tamplefeighane, an anglicisation of Teampull Feichín. The church appears in the Fiants of Queen Elizabeth in a lease dated 16 April 1574, by which one Jasper Horsey, Esq., was granted the tithes of corn and hay, altarages, and other profits from several Kilkenny parishes, including this one, under the designation Lesloynyne alias Tamplefeighane. The lease ran for forty years from the termination of an earlier arrangement made in 1537 between the abbot of St. Thomas the Martyr in Dublin and a small group including a chaplain, a Kilkenny gentleman, his wife, and a local widow, at a rent of £5 6s. 8d. By Carrigan's time the church and churchyard had long been destroyed, though he noted that the circular earthen ring enclosing both could still be traced. That trace has since disappeared too, leaving the 1968 aerial photograph as the clearest evidence that anything was ever there at all.
