Yet for centuries, a substantial residential complex stood there, home to one of the cathedral's senior office-holders, and its footprint survived long enough to be recorded as a ruin well into the nineteenth century before disappearing from view entirely.

The building in question was the Treasurer's Manse, the official residence of the cathedral treasurer, a senior ecclesiastical position responsible for the custody of the cathedral's valuables, relics, and liturgical objects. A formal inquisition carried out in 1546 catalogued the property in careful legal language, describing it as a messuage, three gardens, one orchard, and one tower. A messuage, in the terminology of medieval property law, referred to a dwelling house along with its immediately adjoining land and outbuildings, so the full complex was a meaningful urban estate rather than a modest lodging. The inclusion of a tower suggests a degree of fortification or at least architectural ambition consistent with the status of the office. These details were recorded by Mason in 1819 and later by Clarke in 2002, both drawing on the mid-sixteenth-century inquisition as their source.

The site today lies within the precincts of St. Patrick's Cathedral on the south side of Dublin city. The cathedral grounds are generally accessible to visitors, though the northern close is not a formally marked area of archaeological interest, and nothing visible on the surface now indicates where the manse stood. Those with a particular interest in the medieval topography of the cathedral precinct would do well to consult Clarke's work on Dublin's historic landscape alongside a visit, as the physical remains have long since vanished. What persists is the documentary record, a precise mid-Tudor inventory that captures, in a handful of nouns, the shape of a life lived in the shadow of one of the city's most enduring structures.
