Mineralogy & Petrography

The famous large public displays in halls 1-5 show aesthetic and scientifically valuable minerals, ores, gemstones, rocks (including decorative and building stones) as well as meteorites and impactites (including tektites) collected over more than 500 years. All objects are arranged in a systematic way and new objects are added each year. Special temporary exhibitions may be presented as well in individual halls.
