The spatial configuration of the pre-colonial city of Hanoi was centred around the Imperial Citadel. The city outside the citadel walls was composed of a multitude of villages and the “market district of the 36 streets,” in reference to the commercial specificities of each of the main arteries. The typology of dwellings from this period include the ground-level rural house and the narrowly stacked row houses of two-to-three storeys.
