In the 13th century, the mining of tin placer deposits dominated the Ehrenfriedersdorf mining area. As a result of the mining activity in this first period of mining history, in around 1230 a mining settlement arose near the Sauberg mountain next to an already-present farming settlement. Towards the end of the 13th century, tin placer mining came to a gradual standstill. The heaps of sand and gravel, the waste rock which resulted from placer mining, remain as 13th- and 14th-century witnesses to this original mining activity in the Greifenbach valley.
