Once the world’s tallest building, the Sears Tower was pushed to third tallest when Taiwan's 1,667-foot-tall Taipei 101 was completed in October 2003. At 1,454 feet high, it's still the tallest building in the Western Hemisphere and even has its own zip code. From the 103rd-floor, at 1,353 feet, the Skydeck is the highest observatory in Chicago. On a clear day, you can see Indiana, Michigan and Wisconsin, as well as Chicago area landmarks. "The Sights and Soul of Chicago" interactive display celebrates the city's history in photos, graphics, video and murals. InfoVision kiosks provide online information in six languages.
