The Manchester Mill Ruins in Lithia Springs, Georgia, are the remnants of a textile mill that dates back to the 19th century. These ruins are located in Sweetwater Creek State Park, which is known for its beautiful natural scenery, including the creek itself and a variety of hiking trails that offer views of rapids, wildlife, and historical sites.

The Manchester Mill was operational until it was burned during the Civil War, around 1864, by Union troops under General William T. Sherman during his famous "March to the Sea." The ruins have been preserved as a historical site and are accessible to the public as part of the park. Visitors can see the substantial stone foundations and some of the walls of the old mill, which provide a glimpse into the past and the impact of the Civil War on the industry in the South.

Sweetwater Creek State Park not only offers a look into the history with the Manchester Mill Ruins but also provides opportunities for outdoor activities such as hiking, fishing, kayaking, and picnicking, making it a popular destination for both history enthusiasts and nature lovers.
