The One World Trade Center in New York opens, 13 years after the 9/11 attacks
The One World Trade Center in New York opened for business earlier this week.
The $3.8bn (£2.4bn) building is built on the site of the twin towers of the previous World Trade Center, which were destroyed in the 9/11 attacks in 2001.
The SOM designed 104-storey skyscraper is now the tallest building in the USA. Publisher Condé Nast will
be based there.
