iReport: Your favorite buildings - CNN.com As part of our Great Buildings special, CNN iReport asked you to send in photos and video of your favorite buildings. Here are a selection of the best. John McGraw's image of Grand Central Station, New York was one of several he sent to iReport. Each photo means something special, he says, because of the memories that go along with each trip. "The thought of the millions of people that go through that building, and the history of it, is just spectacular," he said.
