One such structure is a stone house with upper storeys recorded as existing in 1404, known to us only through a single scholarly reference and impossible to pin to any specific address on the modern street map.

The reference comes from Clarke (2002), who notes the house's former existence without elaborating on its occupants or precise function. What the detail does tell us is something worth pausing over: multi-storey stone construction in early fifteenth-century Dublin was not the ordinary domestic arrangement. For most urban inhabitants of the period, timber-framed buildings were the norm, and a stone house rising through several floors would have indicated considerable means, whether the owner was a merchant, a civic figure, or an ecclesiastical interest. The year 1404 places the structure in a period when Dublin, though diminished from its earlier medieval peak, was still a functioning colonial administrative centre under English rule, with a small but prosperous propertied class capable of commissioning substantial town houses.

Because the location has not been precisely identified by researchers, there is no specific site to visit or examine. The south city area broadly covers what is now the Liberties and surrounding streets, a district where archaeological investigations over recent decades have occasionally turned up traces of medieval occupation beneath post-medieval and modern layers. Anyone with a particular interest in the archaeology of medieval Dublin would find Clarke's 2002 study a useful starting point for understanding what survives, even partially, of the built environment from this period. The house itself exists now only as a line in a bibliography, which is perhaps its own kind of archaeological fact.
