During archaeological excavations in 1995, a small watercourse was uncovered, running east to west and reinforced with a timber revetment, a technique in which wooden planking or stakes are used to shore up the banks of a channel and prevent collapse. Modest as it sounds, this narrow cut in the ground may represent the physical remains of a watercourse that shaped the industrial life of medieval Dublin.

The excavation raised the possibility that this channel is what historical sources refer to as Colman's brook. According to research by M. Gowen, published in 1996, the brook was divided into millraces, which are artificial diversions of a watercourse designed to direct the flow of water with enough force to drive a watermill. That a watermill once operated in this part of south Dublin is itself a reminder of how intensively managed the city's waterways once were. Medieval Dublin depended on milling for grinding grain, and controlling water meant controlling a fundamental part of the food supply. Colman's brook, if this is indeed its remnant, would have been a functional artery in that system rather than simply a natural feature of the landscape.

There is nothing to see at ground level today. The watercourse exists now only in the archaeological record, and the site sits within the urban fabric of the south city. For anyone interested in pursuing this further, the excavation report by Gowen remains the primary source, and the broader story of Dublin's lost and culverted watercourses is a well-documented area of urban archaeology. Those with a particular interest in medieval industry or water management might find it worthwhile to cross-reference the location against historical maps of the city, where the line of Colman's brook and its associated millraces may still be traceable as a faint echo in the street patterns and property boundaries that survive today.
