10. The National Museum of the American Indian (1922)

The National Museum of the American Indian was founded by George Gustav Heye in 1922 to house his collection of artifacts from his travels in North and South America. Also located at Audubon Terrace, it sat right across from The Hispanic Society of America. The Audubon Terrace location closed in 1994, and the collection was moved to the former Alexander Hamilton Customs House in the Financial District.
