Windmill, Castleknock, Co. Dublin

A circular water tower now crowns Windmill Hill in Castleknock, on the southern edge of Dublin, and beneath it, somewhere in the ground, lies a criss-cross pattern of buried foundations that probably once supported a working windmill.
There is nothing to see at the surface, no millstone, no post-hole, no worn stonework, just a modest natural hillock that has been quietly absorbing the evidence of its own past.
The hill sits just south of the Castleknock motte, a raised earthwork of the kind built by Anglo-Norman settlers as the base for a timber fortification, and together the two features form the highest points in the surrounding landscape. That elevation would have made the hill a practical choice for a mill; windmills depend on unobstructed airflow, and a natural rise above the tree line and rooftops provides exactly that. When a new water tank was being installed on the hill, a geophysical survey was carried out under Licence no. 07R223. The results, published by Nicholls in 2007, noted a criss-cross pattern of potential interest beneath the surface, interpreted as the likely base of the original windmill. No above-ground remains survived to that point, and none have been uncovered since.
The hill is accessible within the Castleknock area of west Dublin, and the water tower that replaced the mill is still visible as a landmark. Visitors who know to look for it can orient themselves by the proximity of the motte to the north, itself a scheduled monument. The views from the hilltop remain as extensive as they would have been when the mill was operational, taking in a wide sweep of the surrounding landscape. The archaeological interest here is almost entirely sub-surface, so the experience is less about what can be seen and more about standing on a spot where the ground holds more information than the eye can gather.
