The lab aims to simultaneously simulate various conditions that murals and ancient ruins are exposed to so as to collect direct data for future research, said Guo Qinglin, director of the academy's protection and research institute.

Located in the city of Dunhuang, northwest China's Gansu Province, home to the millennium-old Mogao Grottoes, the lab covers an area of 16,000 square meters. It mainly consists of three lab cabins that enable simulation of weather conditions throughout a year, such as windy, snowy and rainy days.

"The lab is adept at testing several tonnes of samples from ancient ruins like the Great Wall that have been exposed to the weather," Guo said, adding that traditional labs could only research on a small amount of samples and are limited in the range of temperature and humidity and experimental time, so experimental results easily deviate from that in the practical environment.

Multi-field coupling lab, with the controlled environment on its merit, will play an important role in basic research of cultural heritage protection, as it is necessary to understand the deep-level mechanism of their degradation when we need to transform from rescue protection to preventive protection of cultural relics, Guo added.

The lab began construction in 2012. It was put into trial operation in August last year and has been running smoothly.
