*** About Willis Tower: The Willis Tower, originally known as the Sears Tower, is a skyscraper in Chicago, Illinois. Standing at a significant height of 1,450 feet, it was the tallest building in the world upon its completion in 1973 and held that status for nearly 25 years. Designed by architect Bruce Graham and engineered by Fazlur Rahman Khan, it's an iconic symbol of Chicago's architectural ambition and capabilities. The building encompasses office spaces primarily and attracts more than a million visitors to its Skydeck each year, from where they can behold sweeping views of the city and beyond. Widely recognized for its distinctive black aluminum and bronze-tinted glass façade, and its bundled tube structure, Willis Tower remains a prime example of architectural innovation and urban prominence.
