In the center of the Myth Hall stands a rock installation, which visualizes and makes the emergence and later mythologization of the Loreley rock emotionally tangible: A fragmenting rock formation rises from the ground, extending through the open ceiling of the exhibition hall into the above stylized Glass Rock. Stone transforms into glass, symbolically releasing the myths and secrets.

Observers of the rock installation in the center of the hall perceive a development and change of the rock. It is brought to life with visual effects and soundscapes. Additionally, a gentle breeze and occasional mists flow along the rock. The stepped area leading to the installation invites visitors to approach the rock, observe, and linger to experience the primal forces, the inherent secrets, and the energies emanating from this place of longing. Furthermore, the myths and secrets are thematized on the walls of the exhibition hall in seven chapters (Echoes).
