The Mile High Illinois, Illinois Sky-City, or simply The Illinois is a visionary skyscraper that is over 1 mile (1,600 m) high, conceived and described by noted American architect Frank Lloyd Wright in his 1957 book, A Testament. The design, intended to be built in Chicago, included 528 stories, with a gross area of 18,460,000 square feet (1,715,000 m2). Wright stated that there would have been parking for 15,000 cars and 150 helicopters.
tallest building in the world by far, being more than four times the height of the then tallest building in the world, the Empire State Building, and twice as tall as the world's current tallest building, the Burj Khalifa, the design of which is said to have been inspired by that of The Illinois.
Wright believed that it would have been technically possible to construct such a building even at the time it was proposed. At the time, the tallest skyscraper in the world was New York's Empire State Building, at less than a quarter the height suggested for the Illinois. It probably would have been possible to erect a self-supporting steel structure of the required height, but there are a number of problems which occur when a building is that tall.
