Brunei–Muara District in the context of "Kampong Ayer"

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.
