A nearly $4 million construction bid has been awarded for the first phase of the renovation of the Corn Palace in Mitchell. Mitchell City Council members scratched out a decorative tile planned for the base of the building, a felt wall finish on the upper floor of the lobby and seven small wind turbines on the south facade of the building. But new all-glass doors for the main entrance pegged at more than $10,000 were added to the project. The two-phase renovation project is expected to cost about $7.2 million. The world's only corn palace was first built in 1892, the Corn Palace serves the community of Mitchell as a venue for concerts, sports events, exhibits and other community events.
