Fulton County. Fulton County, the heart of the Atlanta metropolitan area, is located in the Georgia Piedmont near the foothills of the Blue Ridge Mountains. The Chattahoochee River forms its diagonal border, from the northeast to the southwest.
Fulton County, created from DeKalb County in 1853, spread out in its strange, elongated shape by absorbing the counties of Milton (to the north) and Campbell (to the south) during the Great Depression. It is named for Robert Fulton, inventor of the steam-driven boat.
