5. Omaha Stockyards - On September 17, 1954, the Omaha Stockyards, one of the largest livestock markets in the world, was destroyed by a massive fire. The fire, which started in a livestock pen, quickly spread to other buildings, causing millions of dollars in damage. The stockyards were eventually rebuilt, but by the 1990s, the industry had declined, and the site was closed. Today, the former stockyard site is home to a development known as the South Omaha Campus, including a campus of Metropolitan Community College.
