The Grand Mosque of West Sumatra, built in 1805 by Sultan Muhammad Syah of the Pagaruyung Sultanate, features distinct Minangkabau architecture, as seen in its curved roof resembling the "gonjong" shape. Beyond serving as a place of worship, the mosque is a source of pride for the community and a religious tourism icon in West Sumatra. However, promoting religious tourism faces challenges, particularly for potential visitors who cannot visit the site in person. Virtual Reality (VR) technology offers a solution by providing an interactive and immersive experience without the need to be physically present. This study develops a VR application for the Grand Mosque of West Sumatra, designed to be compatible with Android devices, and explores the ethnomathematical concepts embedded in the mosque's architecture. Ethnomathematics is an interdisciplinary study that connects mathematics with culture and history. The use of VR in ethnomathematical analysis offers deeper insights into the mathematical elements in the mosque's design, such as quadratic functions, rotational symmetry, and other geometric concepts. This research not only promotes the mosque as a religious tourism destination but also enhances public understanding of Indonesia's cultural and historical heritage. © 2026 American Institute of Physics Inc..
