Khmer architecture attained the peak in the period of Angkor era (IX-XIII ages A.D.). Works, dated V age, are although known.

At once it is needed to mark that we know religious buildings only, because the society dwellings were built exceptionally from the wood and aren't save. Architecture of VII-VIII ages is presented little saved prasats — by single temples, in which symbiosis of Khmer architecture and sculpture is already traced. In future the type of architectural buildings changes: separate pracats collect in groups, put on a pedestal, will serve walls, ditches and ductings. Typical Khmer cloister — vat — is a complex of buildings, located on territory, walled in.

The top of Khmer architecture is consider Angkor Vat legally, where only territory of temple occupies an area 1000x850 meters.

At the end of XIX age Cambodian architecture surrenders over to influence of Europe, that is expressed in building of houses of the European type, but however with traditional local elements. At this time the Royal palace and Silver pagoda in Pnompen were created. Today rural houses are built on high wooden piles (if family can afford it), roofs are covered a straw, mats on the floor, done from a palm, and floors — from woven of bamboo stripes, leanings against bamboo beams. A shadow place is used for rest of habitants or storage of food. More well-off families are built edifices with wooden walls and tiled roofs, but a construction remains the same.

French domination left after itself beautiful villas and governmental edifices, built in neoclassical style. Many buildings of the capital are built in neocolonial style.
