Here you have a video with the time-lapse of the construction of the One World Trade Center, which since April 30 has become the tallest building in New York City unseating the Empire State Building.
The One World Trade Center, formerly known as the Freedom Tower or Freedom Tower, is a skyscraper that is being built in New York by architects Thomas Boada and David Childs. This building will be the largest skyscraper of the new World Trade Center complex, replacing the old Twin Towers, destroyed by a terrorist attack on September 11, 2001.
The video summarizes in two minutes eight long years of work in the construction of the tower.
