The Queen Bee Mill is a ruined mill complex located in Falls Park in Sioux Falls, South Dakota. Opened in 1881, the mill operated intermittently for several different owners during the late nineteenth and early twentieth centuries. A 1956 fire led to the site's demolition, leaving the ruins that stand today. The mill site is listed on the National Register of Historic Places. Read more on Wikipedia
