Oculus of the World Trade Center Transportation Hub in lower Manhattan, New York City. The futuristic design by Santiago Calatrava features this soaring oculus. From the outside it looks like a dove spreading its wings, although some have likened it more to a slender stegosaurus. There are 11 subway lines, PATH trains, links to bus and ferry services and a shopping mall. It is adjacent to the 9/11 Museum and Memorial.
