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.
7 months before moving to New York I visited for the first time. I was immediately enraptured and felt a deep connection to the city that I had never experi- enced. It was in this massive hall at The Met that I decided I would be leaving Los Angeles and coming to NYC as soon as I possibly could.
Fav art bookstore in the city (and the world?). Great place for inspiration and reference art, both new and vintage finds. Not very cheap but mostly quite worth it.
