Catoosa County, located along the Tennessee border in northwest Georgia, is the state's 100th county. Catoosa was created from parts of Walker and Whitfield counties in 1853 and comprises 162 square miles.
The Western and Atlantic Railroad built a line through Ringgold, the county seat, which soon became the busiest train stop between Atlanta and Chattanooga, Tennessee.
In 1856 Catoosa County's first courthouse, a two-story brick structure, was built in Ringgold. Soon after its construction, local masons were granted permission to add a third story to the courthouse for a Masonic meeting hall. According to local lore, Union general William T. Sherman did not allow his troops to burn the building in 1864 because of this meeting hall.
