The ancient Potala Palace in Lhasa, Tibet, is perched atop Mount Marpori (meaning “red hill” in Tibetan). It is a treasure trove of the region’s history, culture and art, housing over 100,000 cultural relics. Originally built in the 7th century by Tibetan King Songtsen Gampo, it was later expanded in the 17th century by the fifth Dalai Lama. Listed as a UNESCO World Heritage Site in 1994, it marks the 30th anniversary of this historic recognition in 2024.

As time progresses, this iconic landmark faces challenges from aging and environmental changes. Researchers are leveraging technologies such as digital modelling and advanced monitoring to preserve this priceless cultural treasure for future generations.

The restauration team has captured high-resolution images covering nearly 2,500 square meters of murals and has installed over 1,000 sensors throughout the palace, including crack meters, tilt meters, soil moisture sensors, and air temperature sensors, drawing its “electrocardiogram” for timely health monitoring and warnings.
