Granatium, Mining museum and exhibition center in Radenthein, Austria.
The Granatium is a museum in Radenthein built on the grounds of the former "Isola" costume factory, part of which was converted into exhibition space. Its main building holds a mineralogy display, a garnet room, a gemstone cutting workshop and a shop. A garnet tunnel links the museum to the prospecting area, passing a garnet vein and natural phenomena along the way.
Construction of the present complex began in 2007 on the grounds of the former "Isola" costume factory in Radenthein. The adjacent garnet gorge, where garnets were mined until 1914, was made accessible along its first 200 metres, and part of the factory was converted into a museum. The Granatium opened in May 2008 during the regional exhibition "Kärnten wasser.reich", co-financed by the federal government, the state of Carinthia and the European Union.
The museum's name comes from the garnet stone, and its garnet tunnel hosts concerts and wedding celebrations. In the gemstone cutting workshop, visitors can have the garnets they find cut and finished. The site stands where the Isola costume factory once operated.
The museum is open from May to October with summer hours from 10:00 to 19:00 and offers guided visits. Tours are available in multiple languages, making the visit accessible to international guests.
Visitors can dig for garnets in designated areas and process their finds with professional equipment. The stones can be polished by skilled workers who handle the finishing work on site.
