Cassville is an unincorporated community in Bartow County in the U.S. state of Georgia. It was originally the county seat before the name was changed from Cass County. The seat was moved to Cartersville after General Sherman destroyed Cassville in his Atlanta Campaign of 1864. Cassville, although no longer incorporated, is said to encompass an area beginning at the Cassville Road-Firetower Road intersection and extending a mile in all directions.
