Schloss Freudenstein: Mineralogical collection

Freiberg, Germany

The primary objectives for lighting the Schloss Freudenstein Mineral Museum in Freiberg, Saxony/Germany were: unveil the chemical composition of over 5000 minerals exhibited from different continents; and highlight its 12th-century old medieval architecture. Daylight was an integral component in the entrance and cafeteria. Custom-made luminaires with unique luminance-reducing white-coated lamps were integrated into the architecture in certain exhibition areas with low ceilings to enhance human visual adaptation and give the impression of lighter ceilings. However, halogen, fiber-optic, and fluorescent luminaires with black ceilings were used in other exhibition areas to enrich the geological properties of minerals.
