When I first visited NY in 2010 the New Museum left a permanent impression. I love the architecture and the concept of the piled-white-shoe-box look-a-like building at the edge of the Lower East Side neighborhood. The exhibition program is appealingly different, and the bookstore in the foyer is not to be missed!
If you are in need of a moment of solitude, this is the place. On my first visit I was in awe of how time seemed to stand still inside. It has now become a sanctuary from the city when I need the pace of life to slow down.
