The shah of Iran had an eye for valuable real estate. And so, in their way, did the ayatollahs who toppled him. The shah built the Piaget Building, a glass and granite-striped tower at 650 Fifth Avenue in New York that’s worth at least $800 million, and which courts say is still owned by Iranian fronts.

In late 2013 its storefront lease was bought out for a record $51 million, from Juicy Couture.
