The Willis Tower, previously known as the Sears Tower, is in downtown Chicago. Completed in 1974, it is a 108-story building that held the title of the tallest building in the world for nearly 25 years. It remains the tallest building in the United States. The Skydeck, located on the 103rd floor, is the building's observation deck, approximately 1,353 feet above the ground. It is one of Chicago's most popular tourist attractions, welcoming about 1.3 million visitors annually. Recently, renovations have introduced new glass balconies with floors extending four feet over the street. The balcony provides stunning views of Illinois, Lake Michigan, and neighboring states Indiana, Michigan, and Wisconsin on a clear day.
