UPDATE: Despite being known to some as the Piaget Building, luxury Swiss jeweler Piaget wrote in a statement that "the company does not own the building, nor has it maintained offices there in many years."
The Piaget Building, a skyscraper on 5th Avenue in New York, was one of five locations that federal prosecutors took steps to seize today due to suspicions of links with Iran.
The building is owned by a nonprofit Muslim organization called the Alavi Foundation, at the center of today's activity.
Building data-collector Emporis notes that the 36-story building was erected in 1978 for the Pahlavi Foundation (of the late Shah of Persia). It was built next to the 666 5th Avenue structure in Midtown and replaced the DePinna's department store.
Emporis describes the building further: "The facade is of light brown granite facing, with horizontal stripes of windows on the Fifth Avenue and 52nd Street side, extending also a bit over the corner to the 51st Street side and western facade."
The address of the Piaget Building is 650 Fifth Avenue.
