One hundred and fifty years ago, Louis Seppman a German immigrant finished building a stone windmill on the bluff overlooking the Minnesota River. Designed to grind wheat, the mill has stood the test of time despite losing its blades in a number of windstorms. Today, we are celebrating the amazing achievement of this pioneer and what they brought to this region of Minnesota. Meet “Louis Seppman” and hear some of the stories of early pioneer life on the vast tallgrass prairie and Minnesota River Valley. This program is sponsored by the Blue Earth County Historical Society and Friends of Minneopa. Meet at the Seppman Mill on the campground side of the park.
