If you are a looking for a quiet hiding spot on D.C.'s National Mall, you will find it in one of the two garden courts at the Smithsonian's National Gallery of Art West Building. As a D.C. resident, this is a free and accessible retreat that I do not take advantage of enough.
The Hirshhorn has a panoramic room on their top floor, the National Portrait Gallery has a glass ceiling courtyard created by Foster+Partners, and the National Gallery of Art has this neo-classical garden. This photo was taken on a Sunday afternoon and while the gallery was bustling, the garden was perfectly still.
So, "Here it is, your moment of zen."*
