I love this excellent independent arthouse theater in the Lower East side. Metrograph projects archive quality 35mm and independent films. Tastefully decorated, there is also a candy store, bookstore and restaurant.
The Franklin D. Roosevelt Four Freedoms Park is a four-acre memorial to Franklin D. Roosevelt designed by Louis Kahn that celebrates the Four Freedoms Roosevelt articulated in his 1941 State of the Union address.
Apart from Dia Beacon, in Beacon (upstate New York about an hour away from Grand Central Station) and also the Judd Foundation in Soho, this institution is absolutely one of my favourite places to visit and it is located in Long Island City, Queens. It showcases sculpture in the broadest sense and has an incredible building that used to be a workshop that refurbished and fixed subway cars. It has been running since 1928 and when you visit you will definitely see why that is.
