8. New York Public Library
In season two, Nadia goes researching at the New York Public Library. This scene is actually filmed in the General Society for Mechanics and Tradesmen, a gorgeous library hidden in Midtown that also has a large collection of locks.
Things get a little tricky for Nadia since it’s 1982 and she has to go through the card catalogs. One of the librarians promises to get back to her after doing research on her question.
