The native Raseneisenstein is the base of the Brandenburg-Prussian iron work in Peitz. A factory was built here in 1550. Energy to drive it comes from the Hammerstrom a synthetic river of the Spree. The water of Hammerstrom is between two and three metres higher than in the ponds. Until the 19th century only charcoal was used as fuel. Until 1567 people worked in the iron works at Peitz. From 1809 until 1810 the iron works of today were built. All parts of the factory originate from1839, for example the houses of workers and staff, the factory hall and other places to work. In 1860 work was stopped,but until 1898 a tenant made parts for machines and graves. In the Halls of the factory the Hüttenmuseum was built in 1973. It is a technical museum rebuilt with financial support of the state and the town of Peitz. In the Hüttenmuseum we can find one of the biggest fishing farms of Germany today. It is about 1000 hectars big.
