Blennerville, just over 1km southwest of central Tralee on the N86 to Dingle, used to be the city's chief port, though the harbour has long since silted in. A 19th-century flour windmill here has been restored and is the largest working mill in Ireland and Britain. Its modern visitor centre houses an exhibition on grain-milling, and on the thousands of emigrants who boarded 'coffin ships' from what was then Kerry's largest embarkation point.
