West Sumatra in the context of "North Sumatra"

Vernacular architecture (also folk architecture) is building done outside any academic tradition, and without professional guidance. It is not a particular architectural movement or style but rather a broad category, encompassing a wide range and variety of building types; with differing methods of construction from around the world, including historical and extant and classical and modern. Vernacular architecture constitutes 95% of the world's built environment, as estimated in 1995 by Amos Rapoport, as measured against the small percentage of new buildings every year designed by architects and built by engineers. Vernacular architecture directly influences traditional architecture, a professional and academic practice deliberately and explicitly referencing and continuing local historical traditions and vernacular.

Vernacular architecture usually serves immediate, local needs, is constrained by the materials available in its particular region, and reflects local traditions and cultural practices. The study of vernacular architecture does not examine formally schooled architects, but instead that of the design skills and tradition of local builders, who were rarely given any attribution for the work. More recently, vernacular architecture has been examined by designers and the building industry in an effort to be more energy conscious with contemporary design and construction—part of a broader interest in sustainable design.

Sumatra (/sʊˈmɑːtrə/) is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 482,286.55 km (182,812 mi.), including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago.

Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeastern area contains large plains and lowlands with swamps, mangrove forest and complex river systems. The equator crosses the island at its centre in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid. Lush tropical rain forest once dominated the landscape.

Riau (Jawi: رياو‎) is a province of Indonesia. It is located on the central eastern coast of the island of Sumatra, and extends from the eastern slopes of the Barisan Mountains to the Malacca Strait, including several large islands situated within the Strait. The province shares land borders with North Sumatra to the northwest, West Sumatra to the west, and Jambi to the south, and a maritime border with the Riau Islands and the country of Malaysia to the east. It is the second-largest province in the island of Sumatra after South Sumatra with a total land area of 93,356.32 km², and an estimated population of 7,007,353 in 2024. The province comprises ten regencies and two cities, with Pekanbaru serving as the capital and largest city.

Historically, Riau has been a part of various monarchies before the arrival of European colonial powers. Muara Takus, a Buddhist temple complex believed to be a remnant of the Buddhist empire of Srivijaya c. 11th-12th century, is situated in Kampar Regency in Riau province. Following the spread of Islam in the 14th century, the region was then under control of Malay sultanates of Siak Sri Indrapura, Indragiri, and Johor. The sultanates later became protectorate of the Dutch and were reduced to puppet states of the Dutch East Indies. After the establishment of Indonesia in 1945, Riau belonged to the republic's provinces of Sumatra (1945–1948) and Central Sumatra (1948–1957). On 10 August 1957, the province of Riau was inaugurated and it included the Riau Islands until 2004.

Jambi is a province of Indonesia. It is located on the east coast of central Sumatra and stretches to the Barisan Mountains in the west. Its capital and largest city is also called Jambi. It is bordered by the provinces of Riau to the north, West Sumatra to the west, Bengkulu to the southwest, South Sumatra to the south, and shares a maritime border with the Riau Islands to the east and the Pacific Ocean to the east. The province has a land area of 49,026.58 km, and a sea area of 3,274.95 km. Its area is comparable to the European country of Slovakia or Smolensk Oblast. It had a population of 3,092,265 according to the 2010 census and 3,548,228 according to the 2020 census; the official estimate of population as of mid-2024 was 3,745,746 (comprising 1,893,490 males and 1,830,790 females).

Negeri Sembilan (Malay pronunciation: [ˈnəgəri səmbiˈlan], Negeri Sembilan Malay: Nogoghi Sombilan, Nismilan), historically spelled as Negri Sembilan, is a state in Malaysia which lies on the western coast of Peninsular Malaysia. It borders Selangor on the north, Pahang in the east, and Malacca and Johor to the south. The Arabic honorific title of the state is Darul Khusus (دار الخصوص; "The Special Abode").

The capital of Negeri Sembilan is Seremban. The royal capital is Seri Menanti in Kuala Pilah District. Other important towns are Port Dickson, Bahau and Nilai. The name is believed to derive from the nine (sembilan) villages or nagari in the Minangkabau language (now known as luak) settled by the Minangkabau (or Menangkabau), a people originally from West Sumatra (in present-day Indonesia). Minangkabau features are still visible today in traditional architecture and the dialect of Malay spoken.

Minangkabau (/ˌmēnäŋkəˈbau̇/ MEE-nahng-kah-bow; Baso Minangkabau, Jawi: بهاس منڠكربو‎, IPA: [ˈbaso mi.naŋˈka.bau]), simply known as Minang, is an Austronesian language spoken by the Minangkabau of West Sumatra, the western part of Riau, the southern and western coast of Aceh, the northern part of Bengkulu and Jambi, also in several cities throughout Indonesia by migrated Minangkabau. The language is also a lingua franca along the western coastal region of the province of North Sumatra, and is even used in parts of Aceh, where it is known as the Aneuk Jamee dialect.

Minangkabau is similar to Malay. The relationship between the languages is characterized in different ways. Some see Minangkabau as an early variety of Malay, while others think of Minangkabau as a distinct (Malayic) language.

Bengkulu (Indonesian pronunciation: [bəŋˈkulu], Rejang: ꤷꥍꥏꤰꥈꤾꥈ), historically known as Bencoolen, is a province of Indonesia. It is located on the southwest coast of Sumatra. It was formed on 18 November 1968 by separating out the area of the historic Bencoolen Residency from the province of South Sumatra under Law No. 9 of 1967 and was finalized by Government Regulation No. 20 of 1968. Spread over 20,181.53 km, its land area is comparable to the European country of Slovenia or the U.S. state of Massachusetts or Ivanovo Oblast and it is bordered by the provinces of West Sumatra to the north, Jambi to the northeast, Lampung to the southeast, and South Sumatra to the east, and by the Indian Ocean to the northwest, south, southwest, and west.

Bengkulu is the 28th largest province by area; it is divided into nine regencies and the city of Bengkulu, the capital and the only independent city. Bengkulu is also the 26th largest province by population in Indonesia, with 1,715,518 inhabitants at the 2010 Census and 2,010,670 at the 2020 Census; the official estimate as at mid 2024 was 2,115,631 (comprising 1,065,992 males and 1,020,014 females in mid 2023). According to a release by Badan Pusat Statistik, it has the eleventh highest Human Development Index among the provinces, with a score of about 0.744 in 2013. By 2014, the province is positioned 28th highest in gross domestic product and 20th highest in life expectancy, 70.35 years.

Padang (Indonesian pronunciation: [ˈpadaŋ]) is the capital and largest city of the Indonesian province of West Sumatra. It had a population of 833,562 at the 2010 Census and 909,040 at the 2020 Census; the official estimate as of mid 2023 was 942,938 — comprising 473,089 males and 469,849 females. It is the 16th most populous city in Indonesia and the most populous city on the west coast of Sumatra. The Padang metropolitan area is the third most populous metropolitan area in Sumatra with a population of over 1.7 million. Padang is widely known for its Minangkabau culture, cuisine, and sunset beaches.

The city had historically been a trading center since the pre-colonial era, in both pepper and gold. The Dutch made contact with the city in the mid 17th century, eventually constructing a fortress and taking over control of the city from the Pagaruyung Kingdom. Save for several interruptions of British rule, Padang remained part of the Dutch East Indies as one of its major cities until Indonesian independence. In 1906, Padang, along with Palembang, became the first populated places in Sumatra to achieve city status (gemeente).

The Marapi (Jawi: ماراڤي), or Mount Marapi (Indonesian: Gunung Marapi, Minangkabau: Gunuang Marapi, Jawi: ڬونوواڠ ماراڤي), is a complex volcano in West Sumatra, Indonesia, and is the most active volcano in Sumatra. Like that of its quasi-homonym on Java, its name means "Mountain of Fire". Its elevation is 2,885 metres (9,465.2 ft). Several cities and towns are situated around the mountain including Bukittinggi, Padang Panjang, and Batusangkar. The volcano is also popular among hikers.
