09. The Corn Palace, North Main Street., Mitchell, South Dakota
Mitchell, South Dakota may be a small town, but it sure has a lot of one thing: corn. So in 1892 when the town was trying to lure more farmers to their corn-friendly state, they decided to build a castle in honor of the starchy veggie. The Corn Palace started as a simple wooden structure on Mitchell's main drag, decorated with folk art made from corn husks and kernels. Today this "palace" still exists, and has had a pretty interesting evolution from the initial building.
The exterior of the Corn Palace is decorated every year with a new theme by local artists and the building serves as huge tourist attractions, bringing in half a million visitors a year.
