Imagine yourself in the mysterious world of Siebrandt, a quirky inventor who once lived here and caused a huge bang during one of his experiments, which turned the house upside down. We have never heard of Siebrandt again, but at Mind Mystery we learned everything about him, because despite his absence Angelica and I felt still close to him … At Mind Mystery there is a lot to see and to experience the theme of optical illusions. Visit the museum and discover everything about the great artists, see countless holograms and all kinds of optical art. Get lost in the mirror maze and lose gravity in a gigantic spatial illusion. Play puzzles throughout the park and make the craziest selfies and group photos in Siebrandt’s house, where everything is turned upside down. Increases or decreases in the Ames room and floats above the ground in the square. All this and much more for a pleasant morning or afternoon entertainment at Mind Mystery.
