The mill was built to replace an earlier post mill that stood on the same site since the mid-18th century.
It is a 'towermill' design, which differs from 'smock' mills by having a brick-built structure rather than a timber frame.
The internal gear system is driven by wind power captured through the sails, utilizing a wooden brake wheel and iron main shaft.
The original millers' cottage remains on the premises, reflecting the historical domestic setup of a working mill site.
The restoration project required specialized millwright skills to ensure the sails could turn safely while maintaining historical accuracy.
Waltham Windmill is a six-storey, Grade II listed tower mill originally constructed in 1880. It remains one of the few functional windmills in the United Kingdom that still produces flour using traditional wind-powered milling techniques. The mill features a unique boat-shaped cap and carries four sails, which were restored to maintain its operational status. The site surrounding the mill has expanded into a complex containing a museum, a miniature railway, and various independent craft units. The windmill's internal machinery remains intact, showcasing Victorian-era engineering methods for grain processing. It is maintained by the Waltham Windmill Preservation Society, which facilitates public demonstrations of the milling process. The site is a prominent local landmark in the village of Waltham, located just south of Grimsby. The surrounding grounds are designated as an educational and leisure space for the local community.

Check the windmill's social media or website for active milling demonstration days to ensure you can see the sails in motion.
Allow extra time to explore the small museum on-site, which details the agricultural history of the North East Lincolnshire area.
Bring sturdy footwear, as the paths around the site are gravel and uneven.
Do not attempt to climb the internal ladder systems without an official guide, as the stairways are narrow and steep.
The windmill sails turn only during specific maintenance or demonstration events; museum and shop operations may vary by season.
