The 1836 Lumpkin County Courthouse in downtown Dahlonega, Ga., is home to the Dahlonega Gold Museum Historic Site. Located on the town square, the courthouse is the oldest surviving courthouse building in the state, serving in that capacity until 1965. The state park is a testament to the first major gold rush in the nation. The museum collection includes exhibits about how gold is mined, tools miners used and actual samples of gold. The building features wooden seats from 1889 and the judge’s chambers.
