"The Gimmlitztal is also known as the" valley of the mills ". In 1900 there were still around 23 watermills in the 25 km long tributary of the Freiberger Mulde. Many fell victim to the construction of the Lichtenberg dam around 1970 and no longer exist." - de.wikipedia.org/wiki/Gimmlitztal
The Ratsmühle was the oldest mill in Frauenstein. It was demolished in 1970.
