The foundations, cut down and partially destroyed over the centuries, survive only as fragmentary traces, the kind of archaeology that rarely draws attention but can quietly reframe how a familiar street is understood.

The walls came to light during archaeological monitoring of service trench excavations along Pennyfeather Lane and the nearby Sconce Lane. Monitoring of this kind involves an archaeologist observing groundworks as they proceed, so that anything significant can be recorded before it is disturbed or removed. The work, carried out by Patrick Neary and reported in 2007, identified the foundations on the southern side of Pennyfeather Lane and associated them with houses that were probably constructed along the lane in the early eighteenth century. The street itself, with its evocative name, sits within the Gardens area of Kilkenny, a district whose own name hints at an earlier character, perhaps open ground or cultivated land at the edge of the medieval town before it was absorbed into the expanding urban fabric. The foundations are modest in what survives, but they point to a period when this part of Kilkenny was being settled and built up in a more systematic way.
