One World Trade Center is the tallest building in the Western Hemisphere and the sixth-tallest building in the world. The nearby Oculus, the centerpieces of the World Trade Center Transportation Hub, opened in March 2016. It connects 11 lines of New York city's subway system, New Jersey's PATH rail system, and the Battery Park City Ferry Terminal. Its contemporary design featuring interlocking white steel ribs is reimagined with natural materials by the show's botanical architects.
