Spanning 10 years this EarthCam time-lapse videos shows the construction of the US National 9/11 Memorial Museum in New York.
From Brian Cury (CEO of EarthCam):
A super hardworking team at EarthCam, who I am so proud to work with, spent countless hours keeping the many webcams at the World Trade Center active for 4,617 days… and counting. This unprecedented effort provided our in-house editors with over 1 million images to choose from when creating this two-and-a-half minute video, as well as our other commemorative World Trade Center movies.
