At Abbeyfarm, on the southern edge of Kilmallock in County Limerick, a crossing once spanned the River Loobagh at a point where nothing now breaks the surface of the ground. No stone, no arch, no abutment survives to suggest that anything was ever here at all. The evidence for it is cartographic rather than physical, preserved in a map of the town dating from around 1600, held in Trinity College Dublin as manuscript TCD MS 1209/62.

That early seventeenth-century map places the bridge in a precise and legible relationship with the buildings around it. It sat to the south of the Dominican Friary, a substantial medieval foundation that still survives in partial form above ground, and to the north of a church and its associated graveyard. The River Loobagh, which threads through this part of County Limerick, would have made a crossing here practically necessary for anyone moving between the religious institutions and the wider town. Kilmallock itself was one of the more significant urban centres in Munster during the medieval and early modern periods, and a map detailed enough to record a river crossing at this location suggests the bridge was a meaningful piece of infrastructure at the time of the survey, even if its construction date and materials remain unknown.

Because nothing is visible at ground level, there is no ruin to seek out in the conventional sense. What a visitor can do is read the landscape against the historic map, locating the approximate corridor between the Dominican Friary to the north and the church and graveyard to the south, with the Loobagh running between them. The friary remains are accessible and provide useful orientation. It is the kind of site that rewards attention to what is absent rather than what is present, a gap in the ground where a documented piece of the town's infrastructure once connected two shores and two communities, and where the cartographic record alone keeps the memory of it from disappearing entirely.
