At Kilderry in County Wexford, a north-facing slope beside a small east-west stream is all that marks the supposed site of a church and its associated holy well. There are no visible remains at ground level, no enclosure walls, no stonework, no trace of a well. The field is pasture. What exists instead is a tradition, fragile and inexact, that something was once here.

Local memory has preserved the idea of a church, and the suggestion that a holy well once lay close to the stream to the north of the site. Holy wells in Ireland were typically small sacred springs associated with a patron saint or local cult, often visited for healing or on particular feast days, and frequently found in the company of early ecclesiastical sites. At Kilderry, even that association has worn thin. The name of the well, if it ever had one in common use, is no longer remembered. The church itself is similarly untethered from any recorded dedication, date, or founding figure. What archaeology usually works with, a structure, an enclosure, a name, a saint, is absent here in every respect.
