The Henry Luce III Center for the Study of American Culture on the fourth floor provides public access to nearly 40,000 objects from the New-York Historical Society’s permanent collection. In the Luce Center, visitors can see art and artifacts spanning four centuries, ranging from masterworks of American painting, to the nation’s premiere collection of Tiffany lamps, to historical touchstones such as the draft wheel that played a role in one of the worst urban riots in United States history.
