The wealth of natural rocks, clay, sand and china clay started a small-scale industrialization of the region in the 19th century. The process was especially encouraged by the ceramics industry as well as the extraction and use of the different varieties of porphyry. This development is documented and explained in the geoportal museum Steinarbeiterhaus Hohburg, in temporary exhibitions and along the Georoutes.
The narrow gauge railway network around Mügeln was constructed for transporting agricultural products and china clay. Today, the Döllnitzbahn railway with its steam and diesel trains is a tourist magnet.
