Rumah gadang (Minangkabau: "big house") or rumah bagonjong "house for the Minangkabau people" (Minangkabau: "spired roof house") are the traditional homes (Indonesian: "rumah adat") of the Minangkabau in West Sumatra, Indonesia. The architecture, construction, internal and external decoration, and the functions of the house reflect the culture and values of the Minangkabau. A rumah gadang serves as a residence, a hall for family meetings, and for ceremonial activities. In the matrilineal Minangkabau society, the rumah gadang is owned by the women of the family who live there; ownership is passed from mother to daughter.

The houses have dramatic curved roof structure with multi-tiered, upswept gables. Shuttered windows are built into walls incised with profuse painted floral carvings. The term rumah gadang usually refers to the larger communal homes, however, smaller single residences share many of its architectural elements.

In West Sumatra, traditional rumah gadang reflect the province’s Minangkabau people, and has become the symbol of West Sumatra and Minangkabau culture. Throughout the region, numerous buildings demonstrate the design elements of rumah gadang, including genuine vernacular timber masonry structures built for customary ceremonies, to the more mundane modern structure like those of government offices and public facilities. Today, rumah gadang architectural elements, especially its gonjong horn-like curved roof can be found in modern structures, such as governor and regencies office buildings, marketplaces, hotels, facade of Padang restaurants and Minangkabau International Airport. An istano basa, however, is the largest and most magnificent example of this traditional style.

From the earliest sources of Sanskrit literature, the tree of life is mentioned. The tree of life is the source of all that lives, of all wealth and welfare. The idea of the upper world, underworld, and the tree of life as divine unity is met in many parts of Indonesia.

In some part of Indonesia, there is the tree of life as a sacred tree planted in the centre of the village on a small stone terrace, on the terrace are placed the skulls of sacrificed kerbau (water buffalo). At certain festivities, some times an artificial tree of life is placed and decorated.

In the Javanese shadow play, the wayang kulit, before the performance begins and after its end and also in between the acts a fan-shaped figure is placed in front of the screen. The screen is called gunungan (mountain range) and symbolizes the totality or unity, therefore equivalent to the tree of life. The gunungan may occurs in various forms and all sorts of motifs are worked up in it, but the principal motif is always the tree in the centre, the tree of life.
