1904
The southern part of what is now Midtown was already within the 1889 limits, but in 1904 the City annexes most of the rest of what is now Midtown: this is an area bounded by the 1889 circular city limits on the south, and West Peachtree St. on the west, stretching north up to but not including Ansley Park (roughly 6th to 16th Streets), Piedmont Park, the remainder of Historic Midtown east to what is now the BeltLine. this includes a strip of what is now the Old Fourth Ward between the 1889 limits and the BeltLine.
