England? France? Where in the World?

This is the original Smithsonian Museum on the Mall in Washington, D.C.  It's a very old four-story brick structure that presently houses the administrative offices of the Smithsonain Institution.  It used to be the only building with exhibits.  It takes about 15 minutes to walk from the Washington Monument at one end, to the Capitol at the other end.  Now there are many museums which line the Mall.  I do hope you will come explore this southern city some day soon--Spring and Fall are best.
