In 1848, railway workers embarked on a project to open up trade between the Midwest and East Coast by digging a 1,477-foot tunnel through the base of the Chetoogeta Mountain. Around them, the town of Tunnel Hill sprouted up, as well as Clisby Austin's antebellum-style home, which would go on to serve as a hospital and the headquarters of William Sherman during the Civil War. Train cars eventually outgrew the tunnel, leading to the construction of a larger, parallel tunnel and the retirement of the Western & Atlantic Railroad Tunnel in 1928.
Today, visitors can take a step back in time by walking though the restored tunnel's stone arches or gleaning factual tidbits at the Heritage Center Museum. Civil War reenactments bring the grassy fields to life, as the Federals and Confederates engage in battle and hoop-skirted civilians struggle to stitch up the field's time-space wormhole.
