Vuong Family Residence (Hmong King's Palace)

The Vuong Family Residence, known as the Hmong King's Palace, is a historic fortified mansion in Sa Phin Commune, Dong Van District, Tuyen Quang Province (formerly Ha Giang) within the Dong Van Karst Plateau Geopark. Built between 1919 and 1928 for Hmong leader Vuong Chinh Duc, it combines Hmong, Chinese Qing and French architectural elements. Recognized as a National Relic in 1993, it is notable for its stone walls, wooden structures and historical association with the Vuong family.

Visitors can expect a fortified palace complex set in a valley surrounded by rocky karst mountains in Sa Phin. The site covers about 3,000 sqm with stone perimeter walls, wooden houses with yin-yang tiled roofs, courtyards, and carved wooden pillars and panels. Inside are exhibition rooms displaying furniture, documents, costumes and photographs related to the Vuong family. Visitors can walk through courtyards, living quarters, opium storage areas and defensive structures while learning about Hmong culture and early 20th-century architecture.
