The Freiberg mining district is not only the oldest district, but was also considered the largest and most important mining district in Saxony. More than two-thirds of all Erzgebirge silver was mined here. Additionally, the region also produced copper, lead ore, and other resources. For the purposes of the UNESCO World Heritage nomination, the Freiberg mining region includes the mining landscapes of Gersdorf, the Himmelfahrt mine and Muldenhütten smelting complex, the settlements of Zug and Brand-Erbisdorf, the historic Freiberg old town, and the ore canal and mines in the northern part of the Freiberg district. The Rothschönberger Stolln drainage gallery and the Freiberg RWA active mining water management system demonstrate how water was successfully controlled and used to support mining activities.
