Four World Trade Center opened its doors on Wednesday, becoming the first office tower to open at the original World Trade Center site since the Sept. 11, 2001 terrorist attacks.

A ribbon-cutting ceremony was held to mark the new beginning for the World Trade Center site. Just this past week the same site was involved in a controversy after One World Trade, which stands at 1,776 feet tall, was ultimately ruled the tallest building in the country after the top mast was counted as part of the height. The competition for the tallest tower was between One World Trade and Chicago's Willis Tower.

Just a day later, the news surrounding the site was much more pleasant when the 978 foot tall Four World Trade was finally back in business after more than a decade.

"As we open its doors, the site once again becomes a part of New York's continued growth, reconnected with the city that surrounds it," Mayor Michael Bloomberg said, according to CBS New York.

"That such elegance, beauty and quiet dignity rises from a place once decimated by unspeakable barbarism is as breathtaking as it is uplifting," New York State Assembly Speaker Sheldon Silver said.

Janno Lieber, who has served as the head of World Trade Center construction, elaborated upon the progress that has been made at the site in the last decade.

"We want people to come and experience this both as a great office building, but also a sense of accomplishment that we've really turned the corner on rebuilding the World Trade Center and creating a better New York," Lieber said.
