Sioux City’s second corn palace, built the next year in 1888, was even more splendid than the first. It was built at a new site on the northeast corner of Sixth and Pierce. There was a huge main tower and several smaller towers, and every square inch of the exterior was covered with grain. The only wood showing was on the flagpoles.

The publicity generated by the Corn Palace Train and the successes of the first two palaces led to the grandest festival thus far. Built on the same site as the last palace, (now known as the Corn Palace Lot), the 1889 palace featured a main tower 200 feet high that towered over surrounding buildings.

The biggest palace yet, the 1890 Corn Palace featured a 200-foot main tower and six 100-foot towers. A huge dome, built as part of the largest tower, formed a giant globe with various countries mapped with grains of corn. Of course, Iowa faced front and center with Sioux City most prominently displayed.

The 1891 Palace was so large that it spread across Pierce Street and featured a large archway that allowed traffic to pass through. The palace featured a balcony atop the main 200-foot tower. There, visitors could take in a magnificent view of the city and the surrounding three states.
