The "Cathedral of Light" was a significant architectural feature used during the annual rallies of the Nazi Party in Nuremberg, Germany. Designed by architect Albert Speer, it consisted of a series of powerful searchlights that created a dramatic effect, illuminating the night sky and forming a cathedral-like structure. This spectacle was intended to evoke a sense of awe and unity among the attendees. The Cathedral of Light was first showcased in 1933 and became a symbol of the Nazi regime's propaganda efforts. The lighting display was part of a larger event known as the Nuremberg Rallies, which aimed to promote the ideals of the party and showcase its strength and organization.
