Some vestiges of colonial architecture
Many French architects living in Indo-China borrowed building techniques and decoration patterns from Vietnamese and Chinese architecture.

The few Sa Pa buildings that have survived the wars show how these influences have mingled, with the palace of Hoang A Tuong in Bac Hà as best example. Some of Sa Pa colonial-era villas and the houses along the main road in Muong Khuong testify to this cultural syncretism.
