No wall, no threshold, no carved stone announces where it once stood. Its existence is recorded, but its physical presence has entirely vanished.

The evidence for the school comes from the Friends of Medieval Dublin Map, published in 1978, which plots a St Patrick's School within the cathedral precinct. The Friends of Medieval Dublin was a scholarly initiative that brought together historians, archaeologists, and urban researchers to document the layered medieval fabric of the city before further development could erase it. Their map, catalogued as reference D1, situates the school inside what are now the cathedral grounds, placing it among the cluster of ecclesiastical and civic buildings that once made this part of the Liberties one of the most densely institutional areas of medieval Dublin. The cathedral itself dates to the late twelfth century, with a formal collegiate chapter established in the thirteenth, and schools associated with cathedral chapters were a common feature of medieval ecclesiastical life across Ireland and Britain, providing grammar education primarily for those intended for holy orders or administrative roles. Beyond what the 1978 map records, the historical record for this particular school is thin, and researcher Geraldine Stout, who compiled this entry in 2012, notes plainly that there are no visible surface remains above ground.

Visitors to St Patrick's Cathedral can walk the grounds freely, though access to certain areas may depend on opening hours and any ongoing events at the cathedral. There is nothing to see here in the conventional sense. The value, if anything, is in the act of looking at an apparently ordinary stretch of ground and knowing that the cartographers of medieval Dublin once placed a school somewhere within it. For those interested in the archaeology beneath Dublin's streets, the Friends of Medieval Dublin Map itself is the more rewarding object of study, offering a dense picture of what the city contained before successive centuries of building, demolition, and rebuilding compressed it all into the subsoil.
