Radeberg was mentioned for the first time in 1219, when farmers settled on the country to the large Roeder. The name of the place is probably derived from this river. In less than 150 years a market place, a castle and own units developed. In the year 1412 the municipal law was lent to the small market town.
500 years ago silver was found close of the town. The discovery site thereupon renamed in silver hill. The mine was however fast exhausted.
Its principal industries are the manufacture of glass, machinery, furniture and paper, and it produces a light lager "Radeberger Beer" which is largely exported. The company Elektronik Radeberg GmbH, formerly well known in East Germany for the production of portable television sets, is located there. The Radeberger Brewery was founded in 1872, and is part of the Oetker Group. It brews Radeberger Pilsner, a 4.8% abvpale lager.
