That much is recorded. Where exactly it stood is another matter entirely, and the uncertainty itself tells you something about how thoroughly the early medieval ecclesiastical landscape of this part of Leinster has been obscured by later development and shifting land use.

The evidence for the site comes from the Ordnance Survey Letters, a remarkable series of nineteenth-century field reports compiled as part of Ireland's first systematic mapping project, in which local scholars and antiquarians recorded folklore, placenames, and historical detail townland by townland. The entry cited here, edited by Michael O'Flanagan and published in 1927, notes the presence of a monastery near Tallaght Hill in the vicinity of Corbally. Tallaght itself had genuine ecclesiastical weight in the early Irish church; a significant monastery was founded there, associated with the Céli Dé, a reform movement within Irish monasticism. Whether the Corbally site was a dependency, a satellite settlement, or something older and entirely separate is not recorded. The OS Letters entry is brief and does not venture further than placing it in the general neighbourhood.

Because the site has not been precisely located, there is nothing to visit in the conventional sense. What the record offers instead is a prompt to look at the area around Tallaght Hill with a different kind of attention. The southern fringes of the Dublin Mountains here retain patches of older field systems and occasional placename survivals that hint at earlier occupation. Anyone with an interest in early ecclesiastical geography might usefully cross-reference the OS Letters entry against the relevant six-inch map sheets and townland boundary data, though no surface trace of the monastery has been confirmed. The site remains, in the language of archaeological inventory, not precisely located, which is a careful way of saying that the ground has not yet given up what the documents suggest ought to be there.
