Frohnau is a village in the Saxon borough of Annaberg-Buchholz in the district of Erzgebirgskreis in southeast Germany. The discovery of silver on the Schreckenberg led in 1496 to the foundation of the neighbouring mining town of Annaberg. The village of Frohnau is best known for its museum of technology, the Frohnauer Hammer, and the visitor mine of Markus Röhling Stolln. The mining area around Frohnau has been selected as a candidate for a UNESCO world heritage site: the Ore Mountain Mining Region (Montanregion Erzgebirge).
