Check out this crazy-cool 11-year time-lapse video of the One World Trade Center being built

You'll want to watch this right now. In honor of the opening of One World Observatory, EarthCam recently released an 11-year time-lapse video of the skyscraper being constructed from October 2004 to Memorial Day 2015. The two-minute video contains hundreds of thousands of high-definition images of One World Trade being built from the ground up, but if you're itching to see the view from the inside today, we have our very own incredible photo sequence to share.
