The window itself is narrow, just 0.8 metres high and 0.25 metres wide, with an elliptical head and punch-dressed chamfered surrounds, meaning the stone around its frame was worked with a pointed tool to produce a slightly roughened, dressed finish. It has long since been filled in, but its proportions and detailing survive clearly enough to tell you something about the craftsmen and the era that produced it. The wall it sits in, roughly coursed sandstone rubble standing to about four metres, extends a short distance westward beyond the south wall of 1 Wolfe Tone Street, and that is more or less all that remains above ground.

The building this fragment belonged to would have fronted onto what is now Wolfe Tone Street, and it is possible that further fabric from it was absorbed into the structures at numbers 1 and 2. A document drawn up in 1666, during the post-Cromwellian land settlement, recorded the holdings and occupants of West Gate Lane and Street. It listed over a dozen properties, some slated, some thatched, and a number described as waste or classified as tenements, suggesting a street that had seen considerable disruption in the preceding decades. That list, cited by Burke in 1907, gives a rare glimpse of the neighbourhood as it stood just as the town was being reorganised after years of conflict and displacement. The wall in the yard, with its single sealed window, is a physical remnant of the housing stock that document was trying to account for.
