For the last three years, photographer Benjamin Rosamond has been watching the construction of the 1,776-foot skyscraper at 1 World Trade Center from his living room in Brooklyn. From 30,000 images, Rosamond created this two-minute time lapse video.

There are just a few spots left for one of our popular tours at the ULI Fall Meeting, entitled “The World Trade Site: From Recovery to Rejuvenation.”
