Stock Photo - 22 January 2019, Saxony-Anhalt, Gräfenhainichen: The disused crawler excavator ""Mosquito"" (in front) and the spreader ""Medusa"" are located in ""Ferropolis"", the city made of iron (taken with a drone). A total of five large machines from the former Golpa-Nord open-cast mine were set up here in an orderly fashion and have been setting the stage for an event area with its unique backdrop since 1995. In addition to concerts, several festivals take place here every year. Above all, they are responsible for a steady increase in the number of visitors.
