This panorama was taken from the western edge of Church Hill. The street running left and right through the foreground is 20th street, and the street perpendicular to that is Grace street.
A number of hospital buildings and other significant landmarks can be seen in this photo, the most interesting of which are the Union supply wagons that can be seen on Grace street in front of Seabrook's Warehouse (Gen. Hosp. #9) which is obscured behind the trees.
**note: today, the view from Church Hill is quite similar, though at some point after this photo was taken, 21st street was extended north, and therefore today 21st street will be the street you see in the foreground. However as above stated, the street you see in this photo's foreground is 20th street, and this fact is established by the fact that you can see the roof of Libby Prison (corner Cary and 20th) at far left.
