What survives in the historical record is less a place than a trace: a stone trough, a butcher's kitchen, and a name attached to one of Ireland's most venerated early saints.

Holy wells dedicated to Saint Kevin, the sixth-century monastic founder associated with Glendalough in County Wicklow, were not uncommon across Leinster, and this one was said to have served an ancient monastery in the immediate vicinity. The folklorist Caoimhín Ó Danachair noted it in 1958, drawing on earlier sources to place it near the corner of Montague Street and Camden Street, in what was then the Parish of St. Nicholas. The most vivid account comes from John O'Hanlon, writing in 1873 in his monumental series on Irish saints. O'Hanlon recorded that a stone trough, formerly belonging to St. Kevin's Well, had ended up in the kitchen of a Mr. Donegan, a butcher who lived at the corner of Montague Street. The trough had originally sat within the yard of the house, which itself stood on or close to the site of the well. Whether Donegan was aware of what he had in his kitchen, or whether the trough had simply been repurposed as a convenient vessel, O'Hanlon does not say.

There is nothing to see at the site today. The archaeological record notes that no surface remains are visible, and the junction of Montague and Camden Streets is now thoroughly urban, lined with shopfronts and the ordinary business of a busy Dublin neighbourhood. The value of knowing about this place is not visual but historical: it is a reminder that the city's medieval and early Christian geography did not vanish so much as it submerged, surviving only in the occasional footnote, a scholar's field note, or a stone trough that once caught water people considered sacred.
