No walls, no earthworks, no headstones. What survives is a curved field bank along the townland boundary with Knockbine to the south, tracing an arc of roughly 35 metres, and a local tradition insisting that a church once stood here. The absence of visible remains is itself the puzzle, because the documentary and toponymic evidence points, quite insistently, towards something having existed.

The place name carries the first clue. Tullycanna derives from the Irish Tulaigh Uí Chionaoith, meaning the hillock of Ó Cionaoith, and the Ó Cionaoith family were a medieval ecclesiastical family within the diocese of Ferns. A family name embedded in the landscape, tied to a church institution, is rarely coincidental. The written record adds weight to the tradition. When the lands at Tullycanna were forfeited by Walter Neville in the 1650s, a contemporaneous index recorded not only a castle and a mill on the property but a church as well. After the forfeiture, the land reverted to the Protestant Bishop of Ferns rather than to secular hands, a detail that suggests Tullycanna had been ecclesiastical property throughout its documented history. The site sits within the wider orbit of Ferns, the ancient episcopal centre of County Wexford, where church influence over land and family was deeply embedded from the early medieval period onward.

For anyone walking the ridge today, the curved bank along the southern field boundary is the only physical feature that might hint at something older beneath the grass, though it is subtle and easily overlooked. The connection between that gentle arc and any former enclosure or burial ground remains unconfirmed.
