Apple will be building a massive store in New York’s Grand Central Terminal, we have independently confirmed.

The store will open in the fall, likely early September — and it will be Apple’s largest retail space in the world.

The store already has a name: Apple Store, Grand Central, according to a source close the company. The source said Apple will be making an internal announcement within the next month or so.

“The company will certainly pull out all the stops on this one,” said the source, who asked not to be named.

This year is the 10th anniversary of Apple retail, and Apple wants to make a big splash, our source said. Apple’s retail operation has been a spectacular success, helping fuel the company’s explosive growth and creating shops that make twice as much money as Tiffany & Co.
