That layering of loss on loss is itself telling: the city has been rebuilt so many times, and its documentary record is so uneven, that whole structures of some consequence have simply slipped through the record.

The historian Clarke, writing in 2002, mentions a property known as Cork House as occupying the former site of St Mary del Dam's Church in 1604. St Mary del Dam was a medieval parish church whose name derived from a dam or weir on the Poddle, the small river that once ran more openly through this part of Dublin before it was progressively culverted. The church itself had fallen out of use by the time Cork House appears in the record, which places this building in that restless period following the Reformation when ecclesiastical properties across Ireland were being dissolved, repurposed, or sold off to new owners. Cork House would suggest a connection to the Cork title or its associated families, though the notes do not elaborate further on ownership or the building's precise character.

Because the location has not been pinned down with any certainty, there is no specific address or map reference to offer a visitor. The area in question is the south city, somewhere in the vicinity of what was once the course of the Poddle and the general neighbourhood of Dame Street, which itself takes its name from the same dam that gave the church its distinctive suffix. Walking that part of the city today, between the castle and the river, it is worth bearing in mind that the street layout, the building lines, and even the ground level have changed dramatically since 1604. What looks like an uninterrupted urban streetscape conceals a medieval and early modern geography that scholars are still working to reconstruct.
