Of all the many museums in New York, this one is the most striking to me because of the unique experience you have while viewing the art. This Frank Lloyd Wright building integrates art with architecture in a way that makes it unique to this city. No matter where you are standing you get an incredible, extremely thought out detail of his work and the exhibited work.
This simple Manhattan salt house is shaped like a monumental grain of salt. The Shed is an effort by the city to make even their most utilitarian architecture into unique pieces of art.
This Bookstore has an amazing photography section. I go here to get inspired. You can spend hours in here looking at all kinds of great photography books.
