Built in 1938 on 6-acres of land was the official residence of the Assistant British Resident. Later, it was occupied by the Belait District Officer until 1990. The architecture of the building is a combination of Malay and Colonial designs. The building has been used as a banquet hall during His Majesty’s visit to the district. This was in conjunction with His Majesty’s birthday.
It later became the Belait District Museum containing four permanent galleries and one temporary gallery. The permanent galleries were Cultural Heritage, History of Administration and Development of Belait, History of Oil and Gas, and Natural Heritage. The museum is open to the public from Saturday to Thursday from 9 in the morning to 5 in the afternoon.
