The Chicago Skyline is often ranked as the tallest and one of the most magnificent skylines in the world. It has three of America's five tallest buildings. The Willis Tower (originally the Sears Tower) was once the tallest building in the world and is the second tallest building in the United States. The formation of the Skyline began after the Great Chicago Fire of 1871 which left most of the downtown area destroyed and made it possible to start anew. The Mather Tower, Tribune Tower, and the Chicago Board of Trade, which still exist today, were built during the boom of the 1920s. The second wave of construction happened during the 60s and 70s with additions such as the Sears Tower, the Aon Center, and the John Hancock Center. The third wave is happening currently and includes the Trump Tower, the third tallest building in United States.
