I found this article recently and want to share it with you. I'll paste a piece of text here and a link to freedom tower site.

Few public building projects have sparked such competing emotions as the Freedom Tower. Patriotism has driven it from the start, with some inevitably kitschy results, starting with its height (1776 feet). The building is a solemn monument to the fallen, but also an obvious target, a test of our will and ingenuity to ensure that history doesn't repeat itself.
