A new time-lapse video, made by EarthCam in commemoration of the September 11, 2001 terrorist attacks, shows the nine-year construction of the 1,776-foot One World Trade Center in New York.
EarthCam's network of high-definition cameras captured the incredible footage over the course of October 2004 to September 2013. According to an EarthCam statement, the company hand-edited hundreds of thousands of images that together reveal the striking assembly of the 104-story skyscraper, formerly known as the Freedom Tower.
The special video shows the construction of the One World Trade Center building from the ground up, including the installation of the massive 408-foot, 758-ton silver spire that tops the tower and serves as a broadcast antenna.
In the beginning of the time-lapse clip, the area to the left of the One World Trade Center briefly seen under construction is The National September 11 Memorial and Museum, which now contains rows of swamp white oak trees and acre-sized reflecting pools in the former spaces of the original World Trade Center North and South Towers. Developers plan to complete One World Trade Center in early 2014, while the nearby museum opens in Spring 2014.
