Since the beginning of July 09, the museum has impressed with a completely new exhibition. The showcases were equipped with many new finds and classic mineral specimens (generously and attractively designed). The visitor is given a good picture of the Tujetsch mineral deposits. Between wonderful smoky quartz Gwindel, even the extraordinary milarite of Conrad Berther shines. A must see! The summer opening hours are from 1st July to 31st October, every Tuesday and Thursday from 3pm to 6pm + every 1st Sunday of the month.
