Tipp für Mineralien-Fans: Die geowissenschaftlichen Sammlungen der #TUBAF im Abraham-Gottlob-Werner-Bau sind in sieben Teilsammlungen gegliedert und gehören zu den ältesten geowissenschaftlichen Sammlungen der Welt! Mit einem neuen Kombi-Ticket können Interessierte die Sammlungen zusammen mit der #terramineralia und dem Krügerhaus besichtigen - und haben dafür zwei ganze Werktage Zeit.
