World Trade Center Site in New York City, NY
Construction for 'One World Trade Center' is underway. The new building will be the tallest building in the US and the Western Hemisphere, as well as the world's tallest all-office building. The building is designed to reach 1,776 feet, in celebration of the year of American independence.
The Twin Towers, when they were completed in 1972 and 1973, were the tallest buildings on earth, at 1,368 and 1,362 feet. Before 9/11, they were the fourth and fifth tallest buildings on Earth. They remain the sixth tallest buildings to ever have been built by man. Visitors to the site now can tour the plans and early preparations of the new monument.
