[IMGCAP(1)] Is it a well? Is it a drinking fountain? Or maybe a piece of art? Roll Call challenges you, the reader, to spend the remainder of the August recess trying to find this bit of architecture, located somewhere on Capitol Hill. We’ll tell you where it is when we resume publishing in September.

As for last week’s Lost & Found, we showed the location pictured below and asked you to identify the building housing the courtyard seen through the windows. And the answer is … the Freer Gallery of Art. From the photo, one can see enough of the courtyard to recognize the Renaissance design of the museum. [IMGCAP(2)]
