Standing at 110 stories tall, the Willis Tower is located in Chicago, Illinois and is one of the tallest buildings in the world. I first saw this building as a young child and it had such an impact on me that I will never forget. This is already such a large tower, that seeing it when I was so young made it seem even bigger. I remember thinking it was one of the, if not the, largest thing I had ever seen in my life. I was truly able to understand the true size and beauty of this tower when I visited it again a few years ago and had the chance to go to the top of there tower where I was truly amazed and overtaken with this architectural feat.
