Chrysler building
This took over from the empire state as being the tallest building... for a while. See the spire? Well, when they built it, the architects kept the spire inside the building, and everyone thought it was going to have a flat roof. Then right at the last minute, they raised the spire. Why? There was a competing architect who thought that his building was going to be the highest, but when the spire came up, all hopes were lost.
