China and Italy unite on an international standard for mural conservation

The development of the first international standard for mural conservation is underway under the auspices of ISO, with experts from more than ten countries taking part, including Italy. Key institutions include the Dunhuang Academy, guardian of the Mogao Caves, and Italian conservation specialists.

Why the standard matters

• It provides a shared terminology to describe and classify mural deterioration.
• It creates a systematic framework with illustrated criteria to guide diagnosis and interventions.
• It encourages exchange of best practices and training tools across countries with different contexts.

Comparing the Italian and Chinese contexts highlights technical differences (murals on masonry in Italian churches versus cave murals in China) and complementary strengths: Italy's conservation expertise and China's environmental monitoring technologies can be mutually beneficial.

Implications for UNESCO sites in Italy

• More consistent guidance for assessing and managing mural deterioration in World Heritage properties.
• Increased opportunities for technical cooperation and knowledge exchange between Italian institutions and international partners.
• Useful references for training programmes, funding calls and cultural heritage policies.

Practical advice for visitors to mural sites

• Check for guided tours and ongoing conservation programmes at sites you plan to visit, such as historic churches and the city of Venice.
• Support local conservation efforts through visits, donations or participation in cultural events.
• Follow site rules (no flash photography, keep distance, respect designated paths) to minimize impact on artworks.

International collaboration between Italy and China aims to establish a common technical language and practical tools that strengthen protection of UNESCO-recognised heritage, helping to safeguard fragile murals and painted surfaces for future generations.
