—— Preserving Heritage in a Changing Climate
” Of majestic form and rare in the world ” —— Li Daoyuan
A World Heritage Carved into the Cliff
The Yungang Grottoes, located near Datong in Shanxi Province, China, are one of the most important examples of Buddhist rock-cut architecture in the world. Carved from the mid-5th to early 6th century AD during the Northern Wei dynasty, the site includes 252 caves and niches, more than 51,000 statues and reIiefs, and a carved area of 18,000 square metres.
WhiIe influenced by cave art from South and Central Asia, the Yungang Grottoes developed a distinctive Chinese styIe and local expression. They played an important role in the development of Buddhist cave art in China and East Asia, marking a high point in the earIy phase of Chinese sculpture and religious architecture.

Yungang: A Continuous Historical Record
The Yungang Grottoes still hold deep historical significance today. Religiously, these caves remain a vibrant destination for Buddhist pilgrims from around the world.
Historically, these grottoes represent more than just markers of a single period; instead, they were constructed over multiple dynasties, beginning in the late Northern Wei dynasty and continuing through subsequent eras. Each generation contributed additional layers of artistry and belief, making Yungang not only a masterpiece of early Chinese Buddhist sculpture but also a continuous historical record that has lasted for centuries.

Panoramic VR
720-degree panoramic virtual tours have been developed, allowing remote visitors to explore each grotto in full 3D, zoom into intricate sculptures, switch between languages, and navigate freely across different caves for a personalised experience.

Climate Change Threats
Like many heritage sites around the world, the Yungang Grottoes are increasingly vulnerable to the effects of climate change. Wind erosion gradually wears down the intricate surface details of the sculptures, while air pollution from coal mining and burning contributes to chemical weathering that weakens the rock structure. Rising humidity and increased rainfall further degrade murals and encourage biological growth. Together, these environmental changes accelerate the deterioration of the ancient carvings and pose significant challenges to ongoing conservation efforts.
In response to increasing environmental threats, a variety of protective measures have been implemented at the Yungang Grottoes to help preserve the site for the future. Physical conservation has focused on stabilising the caves and reinforcing weakened structures. At the same time, digital technologies have played a key role in adaptation. High-resolution 3D laser scanning has been used to document the current condition of sculptures and architectural features. These digital records not only assist in restoration planning but also act as long-term archives in case of irreversible damage.

Your Actions Matter: Get Involved
As this exhibition has shown, the Yungang Grottoes are more than just an ancient Buddhist site. They are a living record of cultural exchange and creative devotion that has lasted for over 1,500 years. Today, this extraordinary heritage is under threat — not from war or neglect, but from the growing impacts of climate change. Erosion, pollution, and environmental instability are accelerating the deterioration of the site and many others like it around the world.
Protecting places like this isn’t just a job for professionals. It depends on a wider effort from people who care. Whether that means spreading awareness, supporting sustainable choices, or just sharing what you’ve learned here, every action matters. In working together, we have the chance to protect not only the Yungang Grottoes, but cultural heritage sites around the world — not just for today, but for the generations that follow.
