Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

"Trinity Episcopal Church, 3rd & C & Ind. Ave." Unfinished Capitol in the background, circa 1863-64. View full size. Brady-Handy Collection.
Note that both the Senate and the House were in session when this photo was taken. See the flags flying over each chamber.
It's at 3rd and Indiana. Indiana no longer intersects with 3rd but there's an information plaque in the area which has this exact picture and describes the intersection and the history of it getting torn down to make way for I-395. (Check Google Street View at 526 D St NW to see the plaque, it's next to the Subway Restaurant).
This photo was shot looking NW and shows the East side of the Capitol. The church is long gone and what you would see now is the back of the Annex to the Library of Congress.

I guess the Mall as we know it wasn't there yet. And the Lincoln Memorial site was probably a muddy patch of ground.
