Known as Toberpatrick, it appears on the Ordnance Survey map of 1840 and was once, by the account recorded in that survey's name books, about eight feet square and seven feet deep, with a flight of steps leading down to the water. By the mid-twentieth century the devotions had ceased entirely. By 2005, when archaeologists from Eachtra excavated it under licence, it had been filled with rubble to within roughly seventy centimetres of ground level, and the low enclosing wall visible in a photograph from 1907 had disappeared altogether.

The excavation revealed something of the well's physical complexity, if not its age. Beneath the accumulated debris, the structure proved to be a roughly square revetted void, meaning a stone-lined enclosure built to hold back the surrounding earth, containing within it a smaller, subcircular well on its western base. The original cutting had been made about a metre wider than the walls that were later built into it, with larger limestone backfilled behind them. Up to seven courses of local grey sandstone survived on the south-western side. No artefacts and no dateable organic material were recovered, leaving the date of construction, use, and abandonment entirely open. Excavators noted that the site lies close to a relict pilgrim path that once ran between Mungret Abbey and Templemungret, suggesting it may have begun as a domestic water source associated with that ecclesiastical complex before acquiring religious significance, though the possibility of pre-Christian origins cannot be ruled out. A further connection to the site's devotional life comes from an unexpected direction: the nineteenth-century artist Frederick Burton, whose father owned land immediately south of Mungret Abbey, reportedly drew inspiration for his painting Blind Girl at the Holy Well from Toberpatrick, hinting at the kinds of cures and traditions once associated with it.

A photograph taken by the folklorist Caoimhín Ó Danachair in 1954, now held by the National Folklore Collection at UCD and accessible through the Dúchas archive online, gives a clearer sense of what the well looked like before further deterioration set in. On the ground today, the site sits 4.5 metres east of a field boundary in open pasture, but the depression is heavily masked by scrub and bramble overgrowth, and only the uppermost two steps at the northern edge remain visible. Anyone seeking it out should expect to work for the view.
