Looking up at the skylight inside 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.
