MetLife Building, also known as 200 Park Avenue, is a 808-foot tall skyscraper located right behind Grand Central Terminal in between 42nd Street and 43rd Street, close to One Vanderbilt and Chrysler Building. It was built in 1963 and originally called "Panam" building, it was the largest office tower in the world at the time. It unique design defined Manhattan and its skyline as well, it became a landmark after some time it was completed and still very famous and historic to this day. But, did you know that MetLife Building showed up as the Stark Avengers Tower? That's why we think it's not there but actually served as a partially demolished building as a base for the tower itself.
