It has since vanished so thoroughly from the record that no one can say precisely where it stood, which lends it a peculiar quality among Dublin's lost architecture: a building of clear institutional importance that has slipped entirely out of the city's physical memory.

The deanery associated with Christ Church Cathedral is mentioned by Clarke in 2002, drawing on evidence from 1540, a moment when the cathedral itself was in the final years of its pre-Reformation identity before being refounded as the Cathedral of the Holy Trinity under Henry VIII. A deanery, in this context, would have been a formal residence befitting the administrative head of a cathedral chapter, likely a substantial stone or timber-framed townhouse, and its existence in the south city reflects the dense ecclesiastical geography of medieval and early modern Dublin. The area around Christ Church had long been crowded with clerical properties, chantry houses, and church-affiliated buildings, many of which were dissolved, sold off, or simply absorbed into private hands during the upheavals of the sixteenth and seventeenth centuries. The deanery appears to have been among those that left no lasting trace.

Because the site cannot be precisely located, there is no specific address to seek out, and no surviving fabric to examine. What a visitor to this part of Dublin can do is walk the streets immediately south of Christ Church Cathedral and consider how thoroughly the built environment has been remade across the intervening centuries. The cathedral itself survives, heavily restored in the Victorian period, and the surrounding lanes retain something of their medieval geometry even where the buildings do not. Anyone with an interest in the layers of the city's ecclesiastical past will find the area rewarding, even knowing that one particular building within it has left only a single archival mention and no stone standing.
