The holy well marked on the 1947 revision of the Ordnance Survey six-inch map is, in fact, a relocated version of the original, which still sits roughly forty metres to the south. Whoever consults the map, or visits the current well, is looking at an arrangement engineered by the Flood family, who moved the well to a new position at some point before the early nineteenth century. The water itself, however, never stopped flowing from its original source: a drain carries it underground from the old basin to the new one, so the well is fed by the same spring it always was, just surfacing somewhere different.

The original basin survives intact beside the fosse, or defensive ditch, of a small square rath, the kind of enclosed ringfort that dots the Irish countryside and generally dates to the early medieval period. Writing in 1905, the historian William Carrigan recorded the details of both the relocation and the well's liturgical life. A pattern, meaning a communal gathering held on the feast day of a patron saint, took place at the well each year on the first Sunday of August, continuing until the early part of the nineteenth century. Even that date carried uncertainty: local tradition held that the people who attended were divided over whether the true feast day of St. Dallan fell on the first of August or the third, and no resolution appears to have been reached. That unresolved argument is itself a small, telling detail, suggesting a community still negotiating what it was actually commemorating, and when.
