Historically, buildings like the Hagia Sophia in Istanbul and the Mosque–Cathedral of Córdoba in Spain have embodied different cultural and religious meanings across time. However, examples of a single building simultaneously representing multiple cultural or religious identities remain largely unexplored. In today’s globalized world, driven by technological advancement, people from diverse backgrounds show a growing openness to cultural exchange. This social context shapes the foundation of the project, located in Kuqa County, Xinjiang—once a vital hub on the Silk Road and the capital of the ancient Kingdom of Kucha. Though quieter now, Kuqa remains home to a mix of ethnicities, religions, and cultures. The project is a museum of multi-faith integration. It draws on Islamic arches inspired by Gothic vaults and the traditional Chinese large roof to reinterpret and blend cultural symbols in a contemporary form. While cultural and ideological conflicts persist globally, this design aims to offer a meaningful architectural response—commemorating coexistence through the transformation and renewal of traditional forms in a site rich with historical narrative.
