Freer Gallery of Art & Arthur M. Sackler Gallery

This museum has three claims to fame: it was the first Smithsonian museum dedicated exclusively to art, it houses a fantastic collection of Asian art, and it has perhaps the world's most extensive collection of works by American James Whistler. Charles Lang Freer collected thousand of Asian art and artifacts during his lifetime and also purchased many pieces from his good friend Whistler. The Asian collection has expanded to over 20,000, though the American collection has remained unchanged per Freer's request. The Freer connects to the the Sackler Gallery via an underground exhibition space. METRO: Smithsonian
