Witness the rise of One World Trade Center.

It's been 12 years since the Twin Towers fell. Since 2004 One World Trade Center has floor by floor broken through the New York City skyline. Earth Cam gathered hundreds of thousands of images over the nine years of rebuilding. The skyscraper now stands at 1,776 feet tall.

From October 2004, to September 2013; watch One World Trade Center fill the hole once left in the New York City skyline.
