New York City skyline undergoes dramatic changes 25 years after 9/11

Twenty-five years after the September 11 attacks, the Manhattan skyline has undergone dramatic architectural transformations. New developments such as Hudson Yards and ultra-slender skyscrapers near Central Park have significantly altered the city's visual profile.

At Ground Zero, the new World Trade Center campus features seven glass towers surrounding a memorial consisting of two waterfalls that mark the original footprints of the Twin Towers. While the memorial is widely regarded as successful, the surrounding campus is characterized by heavy security measures, including concrete barriers and police stations, reflecting a heightened state of security in the United States following the attacks. The Oculus, designed by Santiago Calatrava, serves as a luxury shopping hub within this highly regulated environment.
