Its outline survives only as a faint, irregular smudge on aerial photography, the kind of thing that requires digital enhancement and a patient eye to discern at all. That it was once a killeen makes it stranger still. Killeens were informal, unconsecrated burial grounds used for unbaptised infants and sometimes for others excluded from the rites of the established Church; quietly sorrowful places that sat outside the official geography of the dead.

The antiquarian Thomas Johnson Westropp noted the site in a survey published between 1904 and 1905, recording it under the name Templenamona. He traced the name back to a 1586 reference in a survey associated with a man named Peyton, where it appears alongside a designation as a killeen. The name itself carries the Irish word for a church or monastic enclosure, suggesting that whatever function the ground served by the sixteenth century, there may have been an earlier ecclesiastical association. Whether that earlier identity shaped its later use as a killeen is not something the surviving record makes clear, but the layering of meanings compressed into one small, now-vanished site is considerable.

There is little to see on the ground today, and that is rather the point of the place. The earthwork that once defined its boundary has been reduced to something detectable only from above, visible on Digital Globe aerial photographs but not, in any reliable way, to a visitor walking past. Corbally is a residential area close to the city, and the site sits within that ordinary landscape without any marker or formal recognition. For anyone with an interest in landscape archaeology or the quieter margins of Irish religious history, knowing roughly where to look and then finding almost nothing is itself a kind of encounter with how thoroughly the past can be absorbed into the present.
