The World Trade Center (WTC) originally referred to a complex of seven buildings in the Financial District of Lower Manhattan, New York City, primarily built between 1966 and 1975. Its most famous features were the Twin Towers, each with 110 stories, which were the tallest buildings in the world at their completion. The complex was destroyed during the terrorist attacks on September 11, 2001. After the destruction, a new World Trade Center complex has been built on the site, including six new skyscrapers, a memorial, a museum, and other facilities. The tallest building in the new complex is One World Trade Center, completed in 2013, standing at 1,776 feet (541 meters), making it the tallest building in the Western Hemisphere. The original WTC was a symbol of global trade and commerce, designed by architect Minoru Yamasaki. It also included office space, restaurants, a hotel, and exhibition areas. The new complex also features a memorial with reflecting pools marking the original Twin Towers' footprint and a rapid transit hub.
