It appears in the historical record under two names across two centuries, and then, essentially, nowhere else. That kind of quiet disappearance is not unusual for medieval industrial sites, but it makes the fragmentary evidence all the more worth examining.

The historian Clarke, writing in 2002, notes a corn mill on the north side of the city described as an "old corn mill" in a source dating to 1328, suggesting it was already well established by that point. Corn mills of this period were typically water-powered structures used to grind grain into flour, central to the provisioning of any urban settlement, and Dublin's network of watercourses made the north city a practical location for such industry. By 1542, the same general site, or possibly a related one, is referred to as "Poule mill," a name that may reflect a local placename, a family name, or some feature of the waterway that has since been lost along with the mill itself. Clarke does not precisely locate the structure, and no firm identification has been made since.

Because the site has not been pinpointed, there is no specific location to visit, no surviving fabric to examine, and no marker to find. What remains is the paper trail, and for those interested in Dublin's medieval topography, that trail is worth following through Clarke's 2002 work and related archival sources. The north city retains fragments of its medieval street pattern and watercourse history in place-names and in the occasional archaeological find turned up during construction work, so the mill's general territory is not entirely without texture. Anyone drawn to the archaeology of urban milling or the economic geography of medieval Dublin will find this a suggestive, if frustratingly incomplete, entry in the record.
