The development of Bac Ha region at the beginning of the 19th century was slowed down, after the capital was moved to Hue by the Nguyen Dynasty. At the same time, development in Thang Long increased and citadels, cultural structures, temples, and new residential areas were built.

The center of the significant development was in Hue where imposing citadels, palaces, and tombs were built. The Vietnamese culture in Hue was influenced by the gardened-type houses which is quite different from the tubular type of houses in Hanoi.

Hue’s architecture was considered as a collection of traditional influences which relied on flat surfaces, citadel and urban centers, interior decoration, and scenery structures.
