Rayonnant Gothic is a style of architecture that emerged in the 13th century in France, characterized by its emphasis on verticality and light. This style is marked by large stained glass windows, intricate tracery, and a more decorative approach compared to earlier Gothic styles. The term "Rayonnant" means "radiant," reflecting the way light floods into the interiors of these structures. Key examples of Rayonnant Gothic include the Sainte-Chapelle in Paris and the Notre-Dame de Paris renovations. This architectural style aimed to create a heavenly atmosphere, drawing the eye upward and enhancing the spiritual experience within the church.
