Jina Ryu


In 1970 Willis Tower was started and it was finished in 1974. Willis Tower is located at 233 S. Wacker Dr. Chicago, Illinois. It was built because Sears decided to consolidate the thousands of employes distributed throughout the Chicago area into one building on the western edge of Chicago's Loop. It is unique because Willis Tower is the second tallest building in the United States and the tenth tallest freestanding structure in the world.
