World’s Only Corn Palace Mitchell SD – September 2021 This is a quirky roadside attraction we had to see since we passed right by here. All of the artwork murals are made of corn! The palace is a venue for concerts, sports, conferences and parties. Check out the columns in the lobby. They were set up for a party when we were there. Mt. Rushmore made of corn! Close up of a duck mural so you can see the corn in detail.
