The Freibergsdorf Hammer Mill is an old hammer works that was used for metalworking in the village of Freibergsdorf in the German Ore Mountains. The site represents an important witness to proto-industrial development in the Ore Mountains. Of the once-numerous hammer mills, only three others remain working in Saxony: the Frohnauer Hammer, the Dorfchemnitz Iron Hammer Mill, and the Grünthal Copper Hammer Mill.
