The Blennerville Windmill is the largest working windmill in Ireland, a 21-metre stone tower mill built in 1800 on the edge of Tralee Bay. It fell into disuse in the late 19th century, was restored by Tralee Urban District Council in the 1980s, and reopened in 1990 as a working attraction — the sails still turn when the wind permits, and the millstones still grind wheat.
The visitor centre focuses on the Famine emigration history of the Blennerville area, which served as a departure point for ships bound for America during the worst years of the Great Famine. The windmill is about 3 kilometres west of Tralee town centre along the Ship Canal — close enough to cycle or walk.
