The cave of mystery

Next to “The secrets of the Earth” you can enter “The cave of mystery” (3). There, the visitor can experience at first hand the feeling of entering into a natural cave, with stalactites coming down from the ceiling and stalagmites emerging from the floor. All the above are beautifully marked out, by the soft illumination of the cave and the evocative sound of silence, only to be broken by the sibilant noise of bats.
