Traditional architecture in Bali originates from two sources. One is the great Hindu tradition brought to Bali from India via Java. The second is an indigenous architecture pre-dating the Hindu epic and in many ways reminiscent of Polynesian building. Even the Balinese temple, it has been noted, is surrounded by a stone wall dividing its sacred precincts from the village very much like Hawaiian and Tahitian places of worship.

Balinese temples are divided into three parts, one inevitably passes through a split gate or Candi Bentar to enter the first courtyard. Then a second gate rising high with the grinning face of a guardian demon leads to the second division. Inside there are numerous pavilions used for various purposes. In the final courtyard one may find the meru pagoda which may have as many as eleven roofs if the owner or temple is important enough. The black thatch is from the sugar palm and can only be used in temples. There will also stand numerous sanggah or spirit houses and pedestals which will be full of offerings on ritual days. Everywhere carving in brick, volcanic stone and wood will be apparent. All are ringed by walls. The Balinese have always spent a great deal of energy and money on their temples for it is the duty to repay the ancestors for the prosperity.

Balinese royalty has always felt it imperative that they demonstrate their prosperity and standing by building magnificent palaces. The carved wooden doors of these palaces are especially famous for their beauty. The teak doors of the main palace of Denpasar were so large that they required forty porters to carry them. In the palaces bright colours and gold leaf abound for the display of opulence in even the smallest and most insignificant of details is deemed proof of nobility. Unlike Europe, Balinese palaces are not single huge buildings but rather a collection of numerous structures each with a special function such as the bale gede, an open pavilion of 12 columns, where the oldest male of the family sleeps. During important ceremonies like tooth filing this will serve a place to commune with the ancestors and gods who descend from heavens to partake of the many offerings placed on the beds. As in the temple the four directions of the Balinese compass are critical in determining the lay-out and positioning of buildings. There is a developed Balinese science of geomancy written in the ancient palm leaf manuscripts. This is known as Kosala-kosali. Through it we can determine the best place to locate a kitchen for instance. Oftentimes when a family is suffering bad luck or misfortune, the first place the balian or witch doctor will look for is any unwitting violations of the Balinese laws of building. The science of building is held to be a sacred knowledge and traditional Balinese architects who might also be rice farmers were known by the distinguished title of undagi.
