This represents another case of a "phantom" round tower—one recorded in historical literature but lacking verifiable evidence. Archdall, an 18th-century antiquarian, stated that there was a round tower at Farran Church, but this claim was contradicted by the more systematic 19th-century Ordnance Survey investigation.

Conflicting Historical Accounts

The discrepancy between Archdall's account and the OS Letters findings highlights the challenges inherent in early antiquarian research. Archdall's multi-volume work "Monasticon Hibernicum" was groundbreaking for its time but relied heavily on documentary sources, local traditions, and secondhand accounts that were not always verified through direct observation.

The Ordnance Survey Letters, compiled during the systematic mapping of Ireland in the 1830s-40s, involved detailed field investigation and consultation with local informants. Their conclusion that "there was never a round tower in this townland" suggests either Archdall misidentified the location, confused it with another site, or recorded an unsubstantiated local tradition.

Methodological Differences

This case illustrates the evolution of archaeological methodology from the 18th to 19th centuries. Archdall's work, while valuable, reflected early antiquarian practices that sometimes prioritized documentary completeness over field verification. The Ordnance Survey approach, by contrast, emphasised systematic ground-truthing and local consultation.

The Challenge of Lost Monuments

However, the OS Letters' definitive statement should be viewed with some caution. By the 1830s-40s, many round towers had already been demolished or had collapsed, leaving no visible traces. It's possible that a tower once existed but had been so thoroughly destroyed and its stones removed that no memory or evidence remained by the time of the OS survey.

Source Reliability Issues

The contradiction between Archdall and the OS investigation reflects broader problems in Irish archaeological literature, where early antiquarian accounts sometimes created "paper monuments" that influenced later scholars despite lacking physical evidence. Such discrepancies require careful evaluation of source reliability and the circumstances under which different accounts were compiled.

Geographic Confusion

Another possibility is geographic confusion; Archdall may have attributed a round tower from a nearby location to Farran Church, or there may have been multiple places with similar names that led to misattribution. Such geographic confusion was common in early Irish antiquarian literature.

Scholarly Resolution

The weight of evidence favors the OS Letters' conclusion, given their systematic methodology and local field investigation. However, the case serves as a reminder that absence of evidence is not always evidence of absence; particularly for monuments as vulnerable to destruction as round towers.

This "phantom tower" joins other questionable examples like those at Lorum (County Carlow) and the unsubstantiated tower at Kilmacduagh (St. Coman's, County Galway), illustrating how local traditions, documentary errors, or wishful thinking could create archaeological "monuments" that never existed.
