AAA Editor Notes
S. Dillon Ripley Center is entered through a small above-ground, glass-enclosed kiosk at 1100 Jefferson Dr. S.W., between the Freer Gallery of Art and the Smithsonian Castle. Part of the Smithsonian, the center is in an underground complex that houses The Smithsonian Associates, its Discovery Theater and classrooms. It also links the National Museum of African Art and the Arthur M. Sackler Gallery.
