Check Out This Time-Lapsed Video of One World Observatory Over 11 Years [WATCH]

I just stumbled across the coolest video ever! In honor of the opening of the One World Observatory in New York City, EarthCam released a time-lapsed video of the entire building process on YouTube.

You can watch the the structure being built right before your eyes. It's pretty awesome. Construction on the building started in October 2004. It took 11 years to complete.

Now, I have a reason to go to New York again. I want to see these buildings up close and personal!
