Luang Prabang is an outstanding example of the fusion of traditional architecture and Lao urban structures with those built by the European colonial authorities in the 19th and 20th centuries. Its unique, remarkably well-preserved townscape illustrates a key stage in the blending of these two distinct cultural traditions.

Luang Prabang is located in northern Laos at the heart of a mountainous region. The town is built on a peninsula formed by the Mekong and the Nam Khan River. Mountain ranges (in particular the PhouThao and PhouNang mountains) encircle the city in lush greenery.

Luang Prabang is exceptional for both its rich architectural and artistic heritage that reflects the fusion of Lao traditional urban architecture with that of the colonial era. Its remarkably well-preserved townscape reflects the alliance of these two distinct cultural traditions.

The political and religious centre of Luang Prabang is the peninsula, with its royal and noble residences and religious foundations. The traditional urban fabric of the old villages, each with its temple, was preserved by later constructions. The colonial urban morphology, including the network of streets, overlapped harmoniously with the previous model. Formerly the town limits were defined by defensive walls.

The richness of Luang Prabang architecture reflects the mix of styles and materials. The majority of the buildings are, following tradition, wooden structures. Only the temples are in stone, whereas one- or two-storey brick houses characterize the colonial element of the town. The many pagodas or “Vat” in Luang Prabang, which are among the most sophisticated Buddhist temples in Southeast Asia, are richly decorated (sculptures, engravings, paintings, gilding and furniture pieces). Wat Xieng Thong, which dates from the 16th century, comprises an ensemble of the most complex structures of all the pagodas of the town. It is remarkable both from the archaeological point of view, and from the Lao iconographic and aesthetic viewpoint.
Many traditional Lao houses remain; they are built of wood using traditional techniques and materials introduced in the colonial period, such as plaited bamboo panels coated with wattle and daub. Brick colonial buildings, often with balconies and other decorative features in wood, line the main street and the Mekong.

The built heritage of Luang Prabang is in perfect harmony in the natural environment. The sacred Mount Phousi stands at the heart of the historic town built on a peninsula delimited by the Mekong and the Nam Khan, domain of the mythical naga. Ceremonies to appease the nagas and other evil spirits, and Buddhist religious practices (Prabang procession, the monks’ morning quest) perpetuate the sanctity of the place. Natural spaces located in the heart of the city and along the riverbanks, and wetlands (a complex network of ponds used for fish farming and vegetable growing) complement this preserved natural environment.
