Pingyao Ancient City, located in Shanxi Province, China, is one of the best-preserved ancient towns in the country. Originally built during the Western Zhou Dynasty, it flourished during the Ming and Qing Dynasties as a major financial and trade center. The city is renowned for its well-preserved city walls, traditional courtyards, and ancient banking institutions. In 1997, Pingyao was designated a UNESCO World Heritage Site due to its authentic architectural style and historical significance. However, the city faces challenges such as urbanization and tourism pressure. Digital preservation methods, including 3D scanning and virtual tours are being used to document and protect the site while enhancing public engagement. These efforts contribute to United Nations Sustainable Development Goal 11 (Sustainable Cities and Communities) by ensuring the conservation of this invaluable cultural heritage for future generations.
