Hoang A Tuong Castle is located in Na Hoi Tho Hamlet, Bac Ha District, Lao Cai Province; 300m from Bac Ha Market. It is a unique construction work, which harmonizes the Oriental and Western architectural styles.
The castle was built at the beginning of the 20th century (between 1914 and 1921). Its owner was Hoang Yen Chao of Tay origin. He was the father of Hoang A Tuong, a tribal mandarin under the domination of the French colonialists.
The castle covers an area of 4,000mts in which the main building occupies 420mts. In front of its arched doors are earthen banks. Occupying a pivotal position overlooking the Bac Ha valley, the castle serves both as the residence of Hoang Yen Chao, then Hoang A Tuong and as a fortress. Its network of walls, bunkers, and battlements were reinforced by a mortar mixed with sugar molasses. In a distance, the white castle jutting out from the valley looks imposing and majestic.
At present, this castle is put under a restoration scheme to better help tourists get insight into the changes of the local life.
