Civil War Richmond is “an online research project designed to collect documents, photographs, and maps pertaining to Richmond, Virginia, during the Civil War” that has, among other things, a collection of maps of Richmond from around the time of the Civil War.
The map above (source) is described as a “map of Richmond from the Official Records Atlas, Plate LXXXIX, #2. Prepared in 1864 by A. D. Bache for the U. S. Coast Survey.” Civil War Richmond goes on to point out that “this map is flawed in two places – the locations of the Jefferson Davis House and of Libby Prison are both incorrect. The map itself is copied from an 1853 map of the city entitled “Smith’s Map of Henrico County.” Whomever prepared the map for the Union army obviously added these Civil War era features, and got them wrong.”
Interesting changes since then include the reworking of the streets around Jefferson and Chimborazo Parks, and the inclusion of the lettered streets north of Carrington (an area then part of Henrico County).
