[3] Fountain City is located in the Appalachian Ridge-and-Valley region, which is characterized by long, narrow ridges that run in a northeast-southwest direction.
Along with Halls, adjacent communities include Powell, which is opposite Beaver Ridge to the west, Gibbs to the northeast, Beverly to the east, and Whittle Springs to the southeast.
Fountain City is drained primarily by First Creek, which rises near the base of Blackoak Ridge and proceeds southward through downtown Knoxville, where it empties into the Tennessee River.
That same year, the heart-shaped Fountain City Lake was completed, and a railroad known as the "Dummy Line" was constructed to connect the community to Knoxville (its southern terminus was at Emory Place).
Knoxville, seeking to expand its tax base and form a metropolitan government, attempted to annex Fountain City in 1959.
On February 12, 1962, in a ceremony that included a mock funeral for what was deemed the death of Fountain City, the community's leaders handed over a symbolic sword to Knoxville mayor John Duncan.
Fountainhead College of Technology (formerly Smithwood Elementary, then Tennessee Institute of Electronics) was, until recently, located in Fountain City.
