Combining the elements. Sharpening the senses. Implementing great ideas! When the three elements water, air and earth meet in an unique combination like at Marbach Castle, directly on the shore of Lake Constance, the fourth element comes naturally: fire and the spark of enthusiasm. Participants develop their ideas in a perfect conclave. Groups of lone fighters merge into teams. A spectacular ambience ignites emotions. A passionate hotel team fulfills the most diverse of requirements. The fact that a world leader in chocolate and cocoa was once founded here clearly demonstrates that this location is the perfect place to develop big ideas by drawing on all the senses.
