Between the 11th and 13th centuries CE, the Tangut people established the Xixia Dynasty or Western Xia Dynasty in northwest China, a period of great cultural richness and historical significance. The Xixia Imperial Tombs are the largest and best-preserved archaeological site from this era. This celebrated UNESCO World Heritage Site includes nine imperial mausoleums, 271 subordinate tombs, and over 7,100 artifacts that illustrate the multi-ethnic integration and cultural exchanges of ancient China. China's use of advanced laws, technology, and education to protect this invaluable heritage, serves as an excellent model for preservation efforts around the world.
