Sope Creek Ruins, Industrial ruins near Paper Mill Road in Cobb County, United States.

Sope Creek Ruins are the remains of a 19th-century manufacturing facility that spreads along a creek with multiple stone structures. The buildings once processed paper using water power from an upstream dam.

Marietta Paper Mills was incorporated on December 19, 1859, possibly by Andrew Schofield Edmondston and Saxon A. Anderson, and its paper mill supplied Atlanta newspapers. Union soldiers under General Gerrard burned the mill and Denmead's Flour Mill on July 5, 1864; the paper mill was rebuilt in 1865, burned again in 1870, and rebuilt in 1871. Sold at public auction in 1873, it was restructured as the Marietta Paper Manufacturing Company, and paper production ended in 1902.

The ruins show how early manufacturers in Georgia relied on flowing water to power their machines. The site tells the story of how the southern economy depended on such water-powered mills during the 1800s.

The ruins lie along Sope Creek at Paper Mill Road in Cobb County. The largest surviving structure, the mill building, stands about a quarter mile downstream of the road on the east bank; the two-story pulp-grinding mill sits just south of Paper Mill Road. The terrain is wooded and uneven, so wear sturdy footwear.

The largest surviving structure is the mill building on the east bank, about a quarter mile downstream from Paper Mill Road: roughly 300 feet long and containing five rooms. Just south of the road stands a two-story pulp-grinding mill about 100 feet long. The oil room and office sat across a small creek.
