At the corner of Quay Street and Church Street in Dungarvan, a building that looks, to all outward appearances, like a plain 18th-century storehouse is quietly concealing something older. Set into its southern wall are three ogee-headed windows, their distinctively curved and pointed arches a hallmark of late medieval craftsmanship, along with the jambstones of a doorway that predate the present structure by several centuries. It is the kind of detail that rewards a slow walk and a careful eye.

The building's medieval core was substantially remodelled at some point in the 18th century, when it was converted for use as a storehouse. That conversion accounts for its current appearance, which gives little away. The surviving features, documented by John Bradley, Andrew Halpin, and Hilary King as part of an urban archaeology survey of Waterford city and county carried out in 1989, suggest that the original structure belonged to the later medieval town of Dungarvan, a settlement with a significant Anglo-Norman presence and a harbour that made it commercially active throughout the medieval period. The ogee window, characterised by its double-curved arch forming a pointed top, was a fashionable architectural form in Ireland from roughly the 14th century onward, often associated with ecclesiastical buildings but found in high-status domestic and civic structures as well. Its appearance here, in what was apparently a secular building, points to a residence of some consequence.

The building sits at a corner that would have been well within the medieval town's active zone, close to both the waterfront and the church. The jambstones, which are the vertical side-pieces framing a doorway, remain in place despite everything the intervening centuries have done to the fabric around them. There is no interpretive signage to guide the eye, so knowing what to look for makes all the difference: the south wall, the window forms, and the worn stonework that the 18th-century conversion did not entirely erase.
