Brunei

A capital with a river at its centre

Across the Brunei River from the roads and government buildings of Bandar Seri Begawan lies Kampong Ayer, a historic settlement whose houses and walkways stand above the water. Boats connect its neighbourhoods to the city; homes, mosques and community buildings make it part of everyday urban life as well as a record of Brunei’s past. The view offers an immediate introduction to the country: here, water is a place to live beside, travel through and build a city around.^[1][6]

Brunei Darussalam occupies the north coast of Borneo, facing the South China Sea. Its territory is divided into two sections by Malaysia’s Limbang District: the larger western part contains Brunei-Muara, Tutong and Belait, while Temburong lies to the east, surrounded by Malaysian territory apart from its coast. Opened in 2020, the Sultan Haji Omar ‘Ali Saifuddien Bridge gives Temburong a continuous road link to the rest of Brunei across Brunei Bay, avoiding the former route through Malaysia or a boat crossing. The political boundary remains visible on the map, even as the bridge makes travel between districts easier. Temburong’s valleys and forest remain distinct from the western districts. The country’s small size can make it seem self-contained; its coastline, river routes and position on Borneo tie it to a much wider world.^{[2][3][4][26]}

Forests cover much of the interior. In Temburong, Ulu Temburong National Park protects lowland rainforest cut by rivers and ridges. Farther west, Belait’s oil-producing coast and inland forests sit within the same district; Tutong links the capital’s urban orbit to settlements and waterways farther west. Brunei-Muara, the most densely settled district, includes Bandar Seri Begawan, the national capital and administrative centre. Each district meets the sea and forest differently, and the divisions help explain why a journey of a few hours can move between urban neighbourhoods, river settlements and deep green interior.^[3][4]

Warm, humid conditions and heavy seasonal rain feed the rivers that drain this coast. Water connects lowland settlements with interior forests, while tidal reaches bring the sea into daily reach of the capital. Brunei’s rivers carry rain from the interior toward the coast and the sheltered waters of Brunei Bay. They have supported settlement, transport and trade, while the South China Sea links the country to maritime routes across Southeast Asia. Kampong Ayer grew along the Brunei River in this setting. Its stilt houses and water connections are often treated as a striking architectural scene, but the settlement also tells a practical story: communities organized movement, work and public life around waterways long before roads became the dominant form of travel.^[5][6][7]
