A video posted online Thursday shows the National September 11 Memorial and Museum being constructed over the past 10 years.

The footage, which has amassed nearly 150,000 views at the time of publication, was shot by EarthCam.

“It’s been a heroic undertaking to rebuild downtown New York City after the September 11, 2001 terrorist attacks,” Earthcam CEO and founder Brian Cury wrote. “Within days of this national tragedy, I personally installed a camera to webcast the rescue and recovery for the families, and the world, to see the brave determination of first responders.”

“As the recovery effort continued, we installed more cameras to document the rebuilding and construction of the site,” he added. “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.”
