The trend of large windows with stained glass and the tall, vaulted ceilings created a sense of openness. This openness was majestic to the visitors of the church, instilling admiration. The amount of light that the large windows allowed to be let in to the church also created an atmosphere filled with serenity. The light coming in through the stained glass was often considered mystical or divine (Art History Journal).
This serene amazement and inspiring light and spacious cathedral would inspire a sense of divine magic into the space and the visitors would feel as if they have entered a holy place. There was quite the significance of what is holy, and these cathedrals being of holy essence was a goal of this architecture.
