It was a notary house, recorded as existing in 1516, and its exact position has never been established with any certainty.

The reference comes from Clarke (2002, 30), who notes the structure in passing without pinning it to a specific plot or address. A notary house in this period would have served as the working premises of a notary public, one of the legal professionals responsible for drawing up and authenticating documents such as contracts, deeds, and ecclesiastical records. The proximity to St Patrick's Cathedral is suggestive rather than incidental. The cathedral in the early sixteenth century was a significant administrative as well as religious centre, and the presence of a notary nearby would have made practical sense in an era when the church and legal documentation were closely intertwined. Dublin's Liberties district, in which the cathedral sits, had its own distinct legal status, operating outside the jurisdiction of the city corporation, which may have made it an attractive location for certain kinds of professional practice.

Because the site has never been precisely located, there is nothing to visit in any conventional sense. The western approaches to St Patrick's Cathedral are today occupied by the cathedral grounds and the surrounding streetscape, much altered over the intervening centuries. Anyone curious about the area can walk the perimeter of the cathedral and consult Clarke's 2002 study for the broader context of medieval and early modern Dublin, but the notary house itself remains one of those small, stubborn gaps in the urban record, present enough to be noted, too faint to be found.
