In one of his many public appearances following the Sept. 11 attacks, former New York City mayor Rudolph Giuliani promised that the city would rebuild. Twelve years later, that promise has been fulfilled, and we've watched the skyline transform in front of our eyes.
And while social media brands awkwardly try to pay tribute to 9/11, here's a tip: Keep it simple. Sometimes words aren't necessary.
One World Trade Center, or the Freedom Tower, stands at a symbolic 1,776 feet and is the tallest building in the Western Hemisphere. Over the course of nine years it went from groundwork construction from the final touches, and Earthcam captured it all.
The webcam company recorded the nine-year construction progress of One World Trade Center using hundreds of thousands of high-definition images. From October 2004 to September 2013, the company caught nearly every major moment including the installation of the spire back in May.
The photographs were edited into a breathtaking two-minute timelapse video to commemorate the 12th anniversary of 9/11.
