Facing the Ellipse along 17th Street, NW (starting at the intersection of Constitution Ave across from the baseball diamond) are the Organization of American States (1910, Albert Kelsey and Paul Philippe Cret), Daughters of the American Revolution Memorial Continental Hall (1905, Edward Pearce Casey), American Red Cross Headquarters (1917, Breck Trowbridge and Goodhue Livingston), and Corcoran Gallery of Art (1897, Ernest Flagg– now the Corcoran School of the Arts and Design at George Washington University).

The newly completed “E” shaped Department of the Interior (1917, Charles Butler) filling an entire block between 18th and 19th Streets was the first federal building designed for a specific government department. Now the General Services Administration Headquarters, it is often considered the first modern government office building in the country.

Virginia Ave runs diagonally northwest from Constitution Ave towards Foggy Bottom.
