I visited Chicago back in middle school and one of the highlights was visiting the sears tower. This skyscraper was built as an office building for Sears because at the time (1973), Sears was a very big company and was expanding. It is 110 floors high and when you are at the top, you can look over the city and it is the highest from the ground I have ever been. It was a really cool experience and I remember doing research on why the building was designed the way it was built. I think the most interesting part about this tower was that it was just built as an office building for a company. It is an iconic building in Chicago and the biggest one too. This is the best memory I have of Chicago and the biggest structure I have seen in my life. It impacted me in a great way because it was a feeling I will never be able to forget looking down at the city from the top of the Sears tower.
