The shell survives to a height of 7.8 metres, with a diameter of just 3.5 metres, making it a notably slender structure. Opposing doorways face east and west, and several windows remain intact in the masonry, giving the ruin an oddly complete quality for something that has stood without its cap or sails for generations.

The tower sits on a level platform roughly 30 metres across, and around its perimeter faint traces of an enclosing bank are still visible in the ground. This kind of prepared platform was a practical necessity for a working mill, providing a stable, cleared area for carts, grain sacks, and the general business of milling. Windmills were never common in Ireland compared to watermills, partly because the country's many rivers and streams offered a more reliable and controllable source of power. Those that were built tended to appear in areas where watercourses were scarce or inconvenient, and on elevated ground where prevailing winds could be caught consistently. The basal plinth, a thickened course of masonry at the base of the tower, would have helped distribute the considerable weight and vibration of the working machinery above.
