The seat of Franklin County, Chambersburg was founded in 1764 and was originally settled in 1730 by the Chambers brothers, who chose this point at the confluence of the Conococheaque Creek and Falling Spring as the location for their gristmill and sawmill. Chambersburg grew as an important crossroads; it was the point where travelers from east to west crossed the valley that ran from south to north. In the town square, Robert E. Lee made the decision to move east into Gettysburg; Chambersburg itself was occupied three times during the Civil War. Visitors can stroll the charming downtown, shop for antiques, and tour Chambers Fort, the Franklin County Courthouse, and the Old Jail, which was a stop on the Underground Railroad.
