Former village of Rauhenstein

The village of Rauhenstein is or was a good 500 m northwest of the former unrestricted crossing of the Auerbach-Ranna local railway over the Auerbach-Neuhaus state road in the Pegnitz valley. When the city of Nuremberg established and expanded its water protection area, the localities Fischstein and Rauhenstein also had to give way because they were located in this area. From 1970 the 12 individual properties were replaced and then demolished. the ancestral residents were resettled in the course of the following years, the hammer house "castle" fell into disrepair and was demolished in December 1987. Today there is the Hammerherrenhaus ground monument and a display board at the hiking car park.
