There’s one tunnel in particular that residents are curious about. He thinks it runs from underneath Marietta Square to the Courthouse about 50 yards away. Cox says he knows where some of the sealed entrances are, but he’s not telling. Only experts, he says, should explore it.“Some archeologists ought to be the ones to go in them, because if the ordinary public knows where they are, they’re going to be driving these merchants crazy trying to get into them,” Cox says. “And if they get into ‘em, they going to steal what’s in there, if there’s anything in there.” Cox says one resident broke in and told him he found opium bottles. He says he wants to know what this tunnel was used for.“The Department of Interior told me to look for any rings that might be attached to the walls, then it would have been used to hold slaves or it could have been used to put livestock in to help keep down the odor,” Cox says. “And I often wonder did our courthouse records get put down in the tunnels before Sherman burned the courthouse?”City Councilman Griffin Chalfant says there are lots of rumors.“Most people point to the little alcoves in the parking lot by the railroad track, but those were actually coal shoots chutes,” Chalfant says.The only active tunnel he knows of that was part of the Underground Railroad leads into the Marietta National Cemetery. The city is planning to widen sidewalks and plant trees at the square in the coming months.
