The dome of the Crystal Dome was modeled after Sir Richard Buckminster Fuller's (1895–1983) geodesic dome, whose architectural design perfectly reflects the principle of geodesy. Geodesy is the scientific discipline devoted to geographical measurement and representation of the Earth; in mathematics, it designates the shortest path between two points on a curved surface.

Geodesic domes are particularly stable, especially considering the relatively small amount of material used to build them. The dome of the Crystal Dome consists of 595 mirrors that create a special depth effect and give the viewer the feeling of being inside a crystal. Eight of the mirrors are so-called “spy mirrors” that conceal fascinating art objects by various artists. The music in the Crystal Dome was created by Brian Eno. Because it is such a spectacular backdrop, the Crystal Dome is a popular venue for weddings.
