Belait District Museum was built in 1938 on a 6 acre land where it was initially a residence of the Assistant British Resident and later became the official residence for the Belait District Officer until 1990. It is also used to host His Majesty Sultan Haji Jassanal Bolkiah whenever His Majesty visits Belait to celebrate His Majesty’s birthday celebration. This building now becomes a museum where it has five galleries which are Cultural Gallery, History of Administration and Development of Belait District, History of Oil and Gas, Natural History and Temporary Gallery.
