This was a working windmill, and a relatively recent one by the standards of Irish rural industry, constructed sometime before 1837 by a man named R. Jones, the tenant of Ballybrennan, and still shown as operational on the Ordnance Survey's six-inch map of 1839.

Samuel Lewis, writing in his Topographical Dictionary of Ireland in 1837, noted that the mill had recently been erected, which places its construction firmly in the early nineteenth century, a period when improving landlords and ambitious tenants across Ireland were investing in grain-processing infrastructure. The tower is built on a slight rise, a modest but deliberate choice on an otherwise low-lying landscape, giving the sails enough exposure to catch the wind. It measures 8.8 metres in external diameter at the base and 6.2 metres internally, which is a substantial structure. What makes it particularly interesting is how thoroughly it was integrated into the working farmyard around it. The ground-floor entrance faces north, opening directly onto the farmyard, while a wide opening on the east side connected the mill to an attached barn, almost certainly built at the same time. At first-floor level, a second entrance on the south side was accessible from the slope of the hill, and another wide opening to the east again linked the interior to the barn, allowing grain and flour to move between buildings with minimal effort. There is also evidence that the tower once had a third storey, suggesting the original structure was taller and more elaborate than what survives today.

The tower survives almost complete at its current height, which is relatively rare for Irish windmills, many of which were dismantled or reduced once they fell out of use. The careful arrangement of its openings, each positioned to serve a specific function in the milling and storage process, gives a clear sense of how the whole complex was intended to operate as a single, coordinated unit.
