A prior UAE purchase

This is a photo of The Helmsley Building, at 230 Park Avenue, New York, NY. What is so special about this building? It's a fine example of early art-deco styling, and, as it's current name implies, was once owned by Leona Helmsley. It was most recently acquired by the United Arab Emirates 3 years ago. Nothing too exciting there, eh? It's just a 30 story building in Manhattan.
One slight problem, however. As any New Yorker would be able to point out to you, the most important part of this building is it's "basement". Said basement usually referred to by a name that you might be more familiar with than this particular building itself. . .
GRAND CENTRAL STATION. Yes, the very heart and nerve center of the entire New York City public subway system sits under UAE owned real estate. Something else to wonder about. . .
