Vuong family’s maison is located in XaPhin Village, around 25km from the center of Dong Van District. The edifice is a rare historical site which is the witness of Vietnam architecture dated back to Nguyen Dynasty (1804 - 1839) in Ha Giang. Vuong’s edifice consists of 10 smaller houses made of rare wood in giant sizes and roofed with double tiles. Surrounding the structure are rocky walls that are 60-100 centimeters thick and 3 meters high and many lush green trees. It has been classified as a national relic from 1993 and now has become a must-see destination when travelling to Ha Giang.
