The cost of the build came to £210, a fairly precise figure that survives in the historical record and gives the whole enterprise a satisfying, accountable quality. That kind of documentary specificity is not always available for buildings of this period and place, which makes this site quietly interesting even before you consider what it replaced.

The castle that previously occupied the spot was known as Thom Cor Castle, and it appears on a map from 1580 held among the Hardiman Manuscripts at Trinity College Dublin. That it was already being mapped in 1580 suggests it was a structure of some standing in the urban fabric of Limerick at the time, situated as it was in the Irish Town, the older Gaelic quarter of the city that developed separately from the Anglo-Norman Englishtown on King's Island. The castle was demolished in 1696, and the market house was raised in its place, a transition that neatly encapsulates a broader shift in how Irish urban spaces were being reorganised and repurposed in the aftermath of the Williamite Wars. The detail about the castle's demolition and the subsequent build is drawn from the work of Thomas Johnson Westropp, the antiquarian and archaeologist who documented much of Munster's built heritage around the turn of the twentieth century, and from the Urban Survey compiled by John Bradley and colleagues in 1989.

The junction of Mungret Street and John Street is navigable on foot from the city centre and sits within the area of Limerick associated with its pre-Norman and early medieval street patterns. Little of the market house itself survives in any obvious form above ground, so a visit here is more about reading the palimpsest of the street than encountering a standing structure. Coming with a copy of the 1580 map, or at least a familiarity with it, helps orient the imagination toward what this corner once looked like when a castle, rather than a commercial building, marked the junction.
