This paper examines the profound impact of natural light on spirituality and architecture from antiquity to the modern era. It analyzes how different cultures and historical periods utilized natural light to enhance the aesthetic, functional, and spiritual aspects of their architectural designs. Through examples such as the Temple of Luxor, the Temple of Hephaestus, and Hagia Sophia, it reveals how light was used as a fundamental architectural element. Modern architecture, with works by Louis Kahn and Le Corbusier, continues to explore this dynamic interaction, blending historical practices with innovative approaches to create spaces that inspire and enhance human well-being.

Regarding the future, architectural use of natural light is expected to focus on hybrid approaches that combine traditional techniques with technology, creating sustainable and human-centered designs. The integration of adaptive façades, holistic sustainability, and human-centric lighting approaches will play a significant role in shaping environments that nurture, inspire, and sustain human quality of life.
