TU Graz Explores Cultural Heritage Preservation in the Himalayas

Using 3D technology and interdisciplinary expertise, a research team has explored Buddhist temples in the remote Dolpo region of Nepal and digitized them for posterity In the high-altitude and extremely remote region of Dolpo in north-west Nepal, there are numerous Buddhist temples whose history dates back to the 11th century. The structures are threatened by earthquakes, landslides and planned infrastructure projects such as the Chinese Belt and Road Initiative. There is also a lack of financial resources for long-term maintenance….
