Just days after the September 11th attack on the World Trade Centre Towers in New York in 2001, Brian Cury, who works for the Earthcam webcam network, decided to install a webcam at Ground Zero. Initially it was to document the site’s clean-up efforts and, afterwards, the construction of the 9/11 Memorial Museum that began in October 2004 and rounded up this month.

In total, the webcam recorded over a period of 4 617 days and captured over one million images. The end result is this two-and-a-half minute timelapse video created by Earthcam that shows the amazing transformation of Ground Zero.

“This commemorative time-lapse honors the victims of 9/11 and is dedicated to their families and friends, with special gratitude to the first responders and the steadfast construction teams,” explains Cury.
