This one in County Wicklow has none of that. Situated in a south-westerly-facing dip on a sloping grassland, it left no visible remains behind, and by the time anyone thought to record it formally, it had already been forgotten for a generation or more.

The name is the most substantial thing that survives. When the Ordnance Survey mapped this part of Wicklow in 1838, they marked the spot as "Tobervilla" and, in the accompanying OS Letters, defined it as tobar an bhiolair, Irish for "the well of the watercress." Watercress thrives in the cold, slow-moving water that feeds springs and shallow wells, and its presence at a site was often read as a sign of the water's purity or virtue. Whether that association contributed to the well's sacred status, or whether the plant simply grew there in abundance, the name is now the only detail that speaks to what the place once was. O'Flanagan, writing in 1928, noted that the well had already fallen into neglect by the early nineteenth century, which places its abandonment somewhere before 1800 and suggests that whatever pattern or local devotion it once supported had dissolved long before living memory.
