Berambang Island
Berambang Island is situated along the southern bank of the Brunei River in Mukim Kota Batu, Brunei–Muara District, Brunei. As the largest and most populated of Brunei's islands, it holds both historical and ecological significance. The island is home to Tanjong Kindana, where Sultan Muhammad Hasan once established his palace and tomb at the river's entrance. Today, the mausoleum of Sultan Hasan remains a prominent historical landmark.
Geography
Berambang Island, the largest and most populated of Brunei's islands, spans and lies within the Brunei River to the east of the mainland. Its northernmost point, Tanjong Kindana, serves as a key geographical marker for Brunei's eastern approach. This location is distinguished by Bukit Kindana, a -high, densely forested hill located about southwest of the point, crowned by a distinctive cluster of trees.The island's extensive mangroves play a crucial role in supporting Brunei's fishing industry by serving as breeding grounds for fish and crustaceans. The western coast is characterised by mangroves dominated by Heritiera globosa and Nypa fruticans, while the eastern coast features Rhizophora species, with Avicennia stands near Sungai Manunggol. Higher elevations on the island are covered by either secondary forest or cultivated lands. Berambang Island also serves as an essential habitat for the endangered proboscis monkey, which thrives in its expansive, undisturbed mangrove forests. In recognition of its ecological importance, the director of Brunei Museums has proposed designating the island's mangroves as a conservation reserve.
Approximately 575 hectares of Berambang Island consist of mangrove soils, which are grey, clayey, and poorly drained, with potential acid sulfate layers beneath. These soils are periodically flooded during high spring tides, supporting native vegetation dominated by Nypa fruticans. Historically, reclaimed areas of the island have been utilised for the cultivation of rice, rubber, coconuts, and vegetables.
History
Sultan Muhammad Hasan established his palace and tomb at Tanjong Kindana, located at the entrance of the Brunei River. A bridge was constructed under his reign, connecting his palace at Tanjong Kindana to the fortified Chermin Island. While residing at Tanjong Kindana, Sultan Hasan maintained a covered passageway leading to Chermin Island, which served as a defensive stronghold. During his rule or that of his successor, Sultan Abdul Jalilul Akbar, the Spanish reportedly sent an envoy to Brunei. After Sultan Hasan's death in 1598, he was interred in a mausoleum on the island at Kampong Sungai Bunga.Berambang Island's strategic importance became evident during Sir Charles Brooke's tenure as the Rajah of Sarawak. Brooke's occupation of Berambang Island and acquisition of Kota Batu land, stretching along the Brunei River from the consular boundary to Pelambayan and Serdang, raised concerns. Brooke's coal mining operations on the island led to the discovery of crude oil in 1902, at the foot of the hills near Buang Tawar, with production reaching 5,433 gallons in 1911. This oil was used by the Brooketon and Sadong Coal Mining Company in Muara for mining purposes. A blockhouse built during the coal mining era was later dismantled, and its materials were repurposed to build offices, a police station, and barracks in Muara, as noted in a 1915 annual report. By 1924, the island had produced 3,320 gallons of crude oil.
Berambang Island has been designated a wildlife sanctuary under the Wildlife Protection Act to conserve its critical mangrove forests and native species. Three areas—Kampong Riong, Kampong Pudak, and Kampong Tanjong Kindana—have been identified as sanctuaries by the Museums Department. These mangroves provide essential habitats for proboscis monkeys and play a vital role in maintaining the ecological balance of the Brunei River system, supporting mainland urban development.
In 1982, the Ministry of Development proposed preserving 721 hectares of mangroves on the island as a conservation area. The Universiti Brunei Darussalam Biology Department later reinforced this recommendation, citing the mangroves' filtration and fisheries-supporting functions. In the 1990s, plans were introduced to establish a mangrove forest reserve. Berambang Island is also home to Brunei's first commercial fish cage farm, which began operations in the early 1990s. Additionally, under the 2001–2005 National Development Plan, a B$181.5 million housing scheme was proposed, encompassing Kampong Sungai Bunga. In 2001, majority of the buildings are built from concrete, especially on the northern side of the island.
Administration
The island contains six villages: Kampong Berambang, Kampong Menunggol, Kampong Riong, Kampong Sungai Bunga, Kampong Pudak, and Kampong Bolkiah 'B'. Additionally, there is a recreational park called Bukit Bujang Pahang Recreational Park. As of 2021, the island comprised the following census villages:| Village | Population |
| Kampong Buang Tawar | 7 |
| Kampong Riong | 17 |
| Kampong Menunggul | 369 |
| Kampong Pudak | 127 |
| Kampong Tanjong Kindana | 723 |
