Behold the mighty geode. Yes, you can see hundreds of these volcanic bubbles as well as glassy smooth petrified wood, giant boulders of quartz and minerals of various colours. Indeed, crystals brighten up every corner of these lonely academic hallways in the university. The museum is free except for the most interesting section, dealing with the practical uses of crystals in modern day life.

Admission free, exhibition €2.50/1.50.
