Thelnetham Windmill was built in the early 19th Century and is of a tower design with conical cap. Situated on the border between Norfolk and Suffolk this is a working example of what was once a familiar site in the Suffolk countryside. Sadly many mills have fell into disrepair but Thelnetham Windmill looks to be in wonderful condition and the machinery is in pristine condition. Visits are only available by appointment and the windmill can be seen working subject to the weather.
