Oculus interior  is open but all the shops are closed with only a few people in the huge open empty space during the Coronavirus Pandemic.<br />
<br />
The World Trade Center Transportation Hub is a transit and retail complex. <br />
<br />
Designed by Spanish architect Santiago Calatrava, the Transportation Hub is composed of a train station with a large and open mezzanine.<br />
<br />
Oculus resembles a bird being released from a child's hand. The roof was originally designed to mechanically open to increase light and ventilation to the enclosed space. <br />
<br />
This mezzanine is connected to an aboveground head house structure, called the Oculus, located between 2 World Trade Center and 3 World Trade Center, as well as public concourses under the various towers in the World Trade Center complex.
