Terra Mineralia before reopening

07 July 2021, Saxony, Freiberg: This calcite specimen from China, which can be seen in the mineral collection "Terra Mineralia" of the TU Bergakademie in Freiberg, looks like a mountain of potato chips. After an eight-month closure due to corona, the exhibition in Freudenstein Castle reopens to visitors on July 15. The exhibition shows about 3500 crystals, minerals, gemstones and meteorites from five continents. With the start of the summer holidays in Saxony, the museum's educational offers for families also start again.
