Kampung Ayer (kahm-PONG AH-yuhr, Malay pronunciation: [ˈkampoŋ ˈaje(r)], Brunei: Kampung Aing) is a prominent traditional settlement in Bandar Seri Begawan, the capital of Brunei. It comprises neighbourhoods of traditional houses, schools and mosques built on stilts above the Brunei River near the capital's city centre. It has an area of about 10 square kilometres (3.9 sq mi); the total population was 10,250 in 2016. It has been historically nicknamed 'Venice of the East'.
Bandar Seri Begawan (BSB) is the capital and largest city of Brunei. It is officially a municipal area (kawasan bandaran) with an area of 100.36 square kilometres (38.75 sq mi) and an estimated population of 100,700 as of 2007. It is part of Brunei–Muara District, the smallest yet most populous district which is home to over 70 percent of the country's population. It is the country's largest urban centre and nominally the country's only city. The capital is home to Brunei's seat of government, as well as a commercial and cultural centre. It was formerly known as Brunei Town until it was renamed in 1970 in honour of Omar Ali Saifuddien III, the 28th Sultan of Brunei and the father of Sultan Hassanal Bolkiah.
The history of Bandar Seri Begawan can be traced back to the establishment of a Malay stilt settlement on the waters of the Brunei River which became the predecessor of Kampong Ayer today. It became the capital of the Bruneian Sultanate from the 16th century onwards, as well as in the 19th century when it became a British protectorate. The establishment of a British Residency in the 20th century saw the establishment of modern-day administration on land, as well as the gradual resettlement of the riverine dwellers to the land. During World War II, the capital was occupied by the Japanese forces from 1941 and bombed in 1945 upon liberation by Allied forces. Brunei's independence from the British was declared on 1 January 1984 on a square in the city centre.
Brunei–Muara District (Malay: Daerah Brunei–Muara; Jawi: دايره بروني موارا), or simply known as Brunei–Muara (BROO-nei moo-WAH-rah), is the smallest as well as the most populated district in Brunei. It has an area of 571 square kilometres (220 sq mi) and the population of 318,530 as of 2021. The district is also home to its administrative centre is Bandar Seri Begawan, as well as the Brunei International Airport and Muara Port, the country's only international airport and deep-water port respectively. The Brunei River flows within this district and is home to Kampong Ayer. As the administrative center of Brunei is located in the district, it remains the most developed in the country with the most up-to-date infrastructure, despite not being the center of Brunei's main economic activity.
The Brunei River (Malay: Sungai Brunei) is a river which flows through Brunei and empties into the Brunei Bay towards the north-east direction. The Istana Nurul Iman, the official residence of the Sultan of Brunei, stands on its banks. The Brunei River is the shortest major river in Brunei. It is the major river basin within the Brunei-Muara District, the smallest but most populous district. It flows through the country's capital Bandar Seri Begawan. It is home to Kampong Ayer, the Brunei's traditional village on stilts over the river.
