context_page_description: The Seppman Mill is a former windmill in Blue Earth County, Minnesota, United States, now preserved in Minneopa State Park. It was built by Louis Seppmann, a German immigrant, between 1862 and 1864 and is now on the National Register of Historic Places. The sails and internal machinery have been removed.
context_section_description: The stone walls are 32 feet (9.8 m) high and conical. At the base the diameter is 30 feet (9.1 m) and the walls are 2 feet (0.61 m) thick, but taper to 20 feet (6.1 m) across and 6 inches (15 cm) thick at the top. The mill is capped with a wooden dome that could be pivoted on a track to catch the prevailing winds. There was a small platform on the outside of the dome where the miller liked to sit and smoke his pipe. The wooden arms, covered with sailcloth, spanned 72 feet (22 m). The mill had five floors, though some were very short and only held machinery.
