When I was kid we had this set of books in the house that resembled encyclopedias. They were called the 'Books of Knowledge'. I don't know how many times I looked at the pages describing the Empire State Building which was, at the time the books were published, the tallest building in the world; status it held from the time of completion in 1931 until the north tower of the World Trade Centre claimed the title in 1970. When the WTC towers fell following terrorist attack in 2001 the Empire State Building reclaimed the title of tallest building in New York until completion of the One World Trade Centre tower in 2012.
This is the view from the 86th floor observation deck looking south toward lower Manhattan. The 102nd floor observation deck was closed on the day of our visit.
It's been decades since Frank Lloyd Wright's Solomon R. Guggenheim Museum entered by consciousness. It opened in October of 1959, ten years after the death of the man for which it was named and six months after the death of Wright. It's important to include some people in architectural photographs; I persuaded this cute girl from Canada to strike a pose so I could get this picture.
