Not a wall, not a foundation, not a repurposed stone. The only evidence that it existed at all comes from two drawings made within a decade of each other in the late seventeenth century, and from a brief note in a 1932 publication. It is, in the most literal sense, a place that survives only on paper.

The barracks is discussed by Maher, writing in 1932, who places it near the site of what became Clancy Barracks. Its presence is recorded in two contemporary visual sources: Michael Dahl's 'View of Dublin 1690' and a drawing by Francis Place dated 1698. Francis Place was an English artist who visited Ireland in the 1690s and produced a number of topographical drawings of Dublin and its surroundings, works that have since become valuable records of the city's appearance before later development swept much of it away. Dahl, better known as a portrait painter, produced his Dublin view around the same period. That two artists working independently chose to include this structure suggests it was a recognisable feature of the north city landscape at the time, even if its precise form and function remain unclear from the surviving notes.

There is nothing to see on the ground today, and the exact location within Dublin's north city has not been precisely fixed in the available sources. Anyone interested in tracing the history of this site would do better to start in an archive or library than on the street. The Francis Place drawings are among the more accessible of the seventeenth-century Dublin visual sources, and tracking down Dahl's 'View of Dublin 1690' may require some effort; as of a research note from 2009, even the whereabouts of a copy was uncertain. Clancy Barracks itself, on Sarsfield Quay, offers a geographical anchor for anyone trying to orient themselves, but the earlier structure that preceded it in this general area has left the documentary record as thin as the physical one.
