Tate is an unincorporated community in Pickens County, Georgia, United States. The Georgia Marble Company and Tate Historic District in Tate is listed on the National Register of Historic Places. The historic district is centered on GA 53 between GA 5 and Long Swamp Creek.Tate's post office was originally called Marble Works by the United States Postal Service. The area was later known as Harnageville after Ambrose Harnage. The home of Ambrose Harnage was authorized by the Georgia General Assembly to be the first meeting place for county courts for Cherokee County when the county was first established, which functioned as a large territory rather than a true county during the State of Georgia's initial organization of the final Cherokee territory within the state.Elections for a full county government were held in 1832, and court was held at the Harnage house. Prior to that time many county government functions were administered by adjacent counties.
