Fitrah, as the pure and divine innate nature of humans, is a key concept in Islamic worldview that plays a central role in explaining human identity and ultimate purpose. This truth stems from the transcendent realm and the divine origin, which inspire human aspirations and higher instincts. Therefore, understanding and preserving human fitrah is a prerequisite for attaining a virtuous life and forming the foundation of individual and social happiness. This importance extends not only to religious and ethical domains but also to culture and art. This research aims to examine the relationship between the concept of fitrah and architectural art, analyzing how Islamic architecture has been
shaped by inspiration from human fitrah. The study employs a descriptive-analytical method with an comparative approach, investigating the concept of fitrah in Western and Islamic philosophy. By analyzing prominent examples of Islamic architecture, it explores the role of fitrah in their formation. Data collection has been conducted through library and documentary methods. The findings indicate that Islamic architecture arises from the divine fitrah of humans and aligns with their spiritual inclinations. Features such as monotheism, beauty, simplicity, balance, and spirituality, which define this architecture, all manifest the natural dispositions of humans within the context of art and construction. Therefore, a profound understanding of fitrah can serve as a valuable source of inspiration for creating architectural works that elevate human dignity and virtues.
