Visitors walk inside the giant atrium of the Oculus. The Oculus, a futuristic
structure designed by Spanish architect Santiago Calatrava to look like
a dove in flight, is the centerpiece of the World Trade Center transportation
hub in Lower Manhattan in New York City adjacent to the 1 World Trade Center
building. The massive Oculus includes train and subway connections, retail space
and restaurants. Additional photos from New York City are in my Cities gallery.
