A church is recorded here as a monument of note, though the details of its construction, its patrons, and its periods of use remain formally undocumented in publicly available sources at this time.

The name Fiddown derives from the Irish Fid Dúin, meaning something close to "wood of the fort" or "wooded enclosure", which suggests a settlement of some antiquity in the landscape. Churches in this part of Kilkenny frequently have medieval origins, often built on or near earlier Christian foundations, and many were associated with local Hiberno-Norman lordships that took hold in the region from the twelfth century onward. Whether the Fiddown church fits that pattern, or belongs to a later period of construction or ruin, is not something the available record currently makes clear.
