Among the others are Panola Mountain, a 100-acre granite mountain in a state park, added to the register in 1976, and the Rockdale County Jail in Conyers, added in 1982 and now a museum.

Other places of interest in the county include Randy Poynter Lake at Black Shoals Park, a 650-acre reservoir and water sports recreation area stocked with many sport fish varieties; the Lewis Vaughn Botanical Garden, part of the revitalized downtown in Conyers; and the Haralson Mill Covered Bridge, completed in 1997 and the first of its kind to be built in the state since the 1890s.

Perhaps the most well-known place in Rockdale County is the Monastery of the Holy Spirit, a Trappist monastery founded in 1944 on a 1,400-acre plantation once owned by the actress Colleen Moore. The monastery supports itself by selling religious books, art, and other products, and its store is open to the public.

One of the newest attractions in the county is the Georgia International Horse Park, developed for the 1996 Olympics equestrian events and mountain bike competition. Its 1,400 acres now host a wide range of events, from horse shows to wedding receptions.
