A linenhall, to explain the term briefly, was a designated market hall where undyed linen cloth was brought for official checking and exchange, functioning as a kind of regulated clearing house for the trade. That such a structure existed on the south side of the city is itself a small curiosity, given that linen production was far more associated with Ulster, and the better-documented Linenhall in the north of the city.

The evidence for this south city linenhall is cartographic rather than architectural. Charles Brooking's map of Dublin, published in 1728, marks the building, and John Rocque's far more detailed survey of 1756 confirms its presence in the same general area. Rocque's map is a particularly reliable source; his work was meticulous by the standards of the day, and structures he chose to label were generally of some civic or commercial significance. The fact that both maps, separated by nearly three decades, record the linenhall suggests it was a functioning and recognised feature of the urban landscape across at least that period, not a fleeting or minor enterprise.

Because the building's precise survival, current condition, or exact street address are not documented in available records, a visitor today would be working from the maps themselves as a starting point. Both Brooking's 1728 map and Rocque's 1756 map have been digitised and are accessible through institutions such as the Dublin City Library and Archive, where staff can assist with cross-referencing historic plot locations against the modern streetscape. Anyone with an interest in tracing the site would do well to begin there, comparing the old cartography with current Ordnance Survey layers to narrow down which block or lane the linenhall once occupied. The south city's street pattern, in places, has changed considerably since the mid-eighteenth century, so the exercise requires some patience, but the maps themselves are worth examining simply as documents of how the city was understood and organised at the height of Ireland's linen trade.
