The walls are fragmentary, the stonework tumbled, and nothing announces the site's presence. What survives is modest by any measure, yet it represents the working infrastructure of a domestic estate that predates the park itself by several hundred years.

The mill is associated with a dower house, a residence traditionally set aside for a widow of the estate, dating to the sixteenth century. The remains consist primarily of a section of wall running east to west, built from water-rolled boulders, the kind of rounded stone shaped by river or coastal action rather than quarried directly. These have been bound together with heavy mortar and still stand to three courses in height, reaching roughly a metre in width and just over six metres in length. The wall leans slightly outward, a condition described in survey records as battered, meaning it tapers as it rises, a technique sometimes used to add stability. At the eastern end, a second wall runs at a right angle, standing to about forty-five centimetres. This perpendicular section appears to have formed one side of a millrace, the channel that directed water onto or beneath the mill wheel to drive the machinery. Considerable stone has collapsed across the surrounding ground, suggesting the original structure was more substantial than what now remains.

The site sits within St Anne's Park, the large public park that runs between Raheny and Clontarf on Dublin's northside. Access to the park is straightforward, with entrances from the Clontarf Road and Mount Prospect Avenue among others. The north-eastern section of the grounds tends to be quieter than the rose garden and the main open areas, and the mill remains are unenclosed and unmarked in any formal way. Visitors searching for the site should expect to look carefully; the stonework blends into the surrounding vegetation and the collapse of material across the area makes it harder to read as a coherent structure. The low height of the surviving walls means the millrace channel, if it can be identified at all, requires some patience to interpret on the ground.
