J.P. Eisentraut designed the Elks Lodge in 1911, combining lavish clubrooms and offices on upper floors with storefronts at street level. The yellow brick, Mission-style edifice displays concrete detailing. The foundation reportedly contains dinosaur footprints. Upper-story windows are Chicago-school style.
The Elks Theatre was originally a lavish opera house that became an entertainment showplace in the heyday of live theater. The movie theater that now occupies the opera house boasts the large movie screen in South Dakota. It also hosts live performances as well. On the top floor, in a former ballroom, the Elks Theater has a second screen.
