Digitally Preserving the Indigenous Architectural Heritage of China’s Dong Minority
An academic project has utilized advanced 3D scanning and documentation to preserve the vulnerable Indigenous architectural heritage of China's Dong ethnic group, protecting their historic villages and unique cultural structures from the risks posed by climate change and rapid modern development.
Highlights
- •The Dong people, an Indigenous group in southwestern China, have maintained a rich oral culture for 600 years.
- •A university-led research project, Decoding Dong, has successfully digitized 100 historic architectural structures.
- •Traditional villages face growing threats from climate change, rapid urban expansion, and poorly managed rural tourism.
- •The project utilized advanced technologies like 3D LiDAR scanning and photogrammetry to create permanent digital records.
The Dong people, an Indigenous ethnic group residing in the mountainous regions of southwestern China for approximately six centuries, are currently the focus of a vital digital preservation initiative. Lacking a written language, their vast cultural knowledge has traditionally been passed down through oral history, leaving their unique way of life largely unknown to the wider world. A specialized academic research project is now capturing their Indigenous architectural heritage to ensure these traditions are not lost to time.
With an estimated population of 3 million spread across Guizhou, Hunan, and Guangxi provinces, the Dong are widely recognized for their intricate polyphonic choral singing, which is listed as UNESCO intangible cultural heritage. However, their physical environment—characterized by refined agricultural terracing and distinct wooden architecture nestled within fir forests—has remained largely undocumented until the launch of the Decoding Dong project.
Preserving Indigenous Architectural Heritage in a Changing Landscape
Typical Dong settlements feature specialized structures such as the iconic wind-and-rain bridges, which serve as both territorial markers and communal gathering spaces. At the heart of these villages, one usually finds a drum tower, representing clan kinship, and a Sa-Sui shrine, dedicated to the worship of the "Sa," or grandmother. These structures are essential for the social, spiritual, and security needs of the community.
However, this Indigenous architectural heritage is under significant threat from various modern pressures. Climate change has led to increased risks of mountain flooding and wildfires. Furthermore, rapid urban expansion, coupled with the growth of rural tourism, threatens to alter the authentic character of these historic villages. In some instances, traditional designs are being replicated as superficial theme park attractions, stripping them of their cultural context and connection to the surrounding landscape.
To combat these risks, the Decoding Dong project, which ran from 2023 to 2025, employed a multidisciplinary approach to capture the physical and cultural essence of these sites. The team utilized advanced technologies, including 3D LiDAR scanning, aerial and terrestrial photogrammetry, and 3D reality capture modeling. These technical methods were combined with oral histories gathered directly from community members, ensuring a holistic documentation process.
By successfully documenting roughly 100 historic buildings across twelve remote villages, the initiative has provided a vital digital repository. This record not only honors the Dong people's legacy but also aims to raise global awareness regarding the challenges of maintaining such distinct traditions amidst modernization. The project highlights a path forward, proving that cutting-edge technology can play a crucial role in safeguarding fragile, historic environments for future generations.
