World's Only Corn Palace is at jct. Sixth and Main sts. at 604 N. Main St. Established in 1892, this Moorish-style building is accentuated with domes, corn murals and a balcony. An Oscar Howe exhibit, historical timelines, a walk-out balcony and custom designed domes that are lit at night are in the lobby. Portions of the exterior and interior are covered with murals made from ears of corn; local grasses and grains form the outline of the designs.
The motif is changed each year, and redecorating has become an annual event that begins in early June. Some 375,000 ears of corn and more than 3,000 bushels of native grains and grasses are used during the process. The interior contains wall panels designed by South Dakota artists Oscar Howe and Cal Schultz. The building is illuminated at night.
The original intent of “The Corn Belt Exposition,” as the building was first known, was for farmers to display the fruits of their harvest, thus showcasing the region's fertile soil and agricultural bounty. Guided 20-minute tours are offered in the summer. The Corn Palace Festival, held in August, features concerts and a carnival.
