In recognition of the opening of One World Observatory in New York City, EarthCam has published a full time-lapse of One World Trade Center's construction. Thousands of high-definition images capture the incredible undertaking of construction and planning that took place from October 2004 to Memorial Day 2015. The camera flies the viewer across the site, showing how the building and its surroundings have taken shape over the past 11 years.
