The Chicago Athenaeum Museum of Architecture and Design is an international museum in Chicago known for its 20th-century architecture. The Museum is dedicated to showcasing the key features and history of the city's architecture, as well as the early examples of modern technological inventions such as the telephone, television, toaster, and other appliances. Its mission is to educate the public about the value of good design in all areas of the discipline, including architecture, industrial and product design, graphics, landscape architecture, and urban planning. The Museum emphasizes how design can positively impact the human environment, from the "spoon to the city."

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.
