Seppman Mill, Stone windmill in Blue Earth County, Minnesota, US.
The stone structure stands 32 feet high with a diameter of 30 feet at the base, featuring a rotating wooden dome to catch wind currents.
German immigrant Louis Seppmann constructed this mill between 1862 and 1864, using his skills as a stonemason and mechanical expertise to carve wooden machinery.
The mill represents early European settlement in Minnesota, demonstrating the transfer of traditional German milling techniques to the American frontier.
The interior remains closed to visitors, but the exterior can be viewed during Minneopa State Park operating hours throughout the year.
At its peak operation, farmers traveled up to 30 miles to grind their wheat, with the mill processing 150 bushels per day under favorable conditions.

Minnesota contains numerous locations away from the main tourist circuits. The state stretches from the shores of Lake Superior to the southern prairies, encompassing historic lighthouses, underground mines, waterfalls, and Japanese gardens. Visitors find both natural landscapes and cultural sites that tell the story of the region's history. Notable locations include prehistoric rock carvings at Jeffers Petroglyphs Site, where indigenous peoples left their marks thousands of years ago, and sacred trees of Ojibwe culture. The geological formation known as Devil's Kettle, a waterfall whose course puzzled scientists for years, attracts visitors interested in natural phenomena. Historic mines provide insight into Minnesota's industrial past, while lighthouses recall the maritime history along the largest of the Great Lakes.
