Istana Kota Manggalela, Royal palace in Kuala Belait, Brunei

Istana Kota Manggalela is a palace on Jalan Maulana in Kuala Belait, built entirely of concrete and cement. It was begun in 1956 and finished two years later as a temporary residence for Sultan Omar Ali Saifuddien III, and was first called Istana Hinggap, from the Malay word for "temporary".

Istana Hinggap was built in 1956 and completed two years later, ordered by Sultan Omar Ali Saifuddien III as a temporary residence for his visits to Belait District. From the 1960s to the 1970s it served as a stopover point for British Army officers. It now functions as a tourist attraction and historical site.

The name Istana Kota Manggalela comes from a battle fought around Manggalela Fort in Beaufort, Sabah, during the Padas Damit War, when British North Borneo Company forces faced Bruneian Sultanate residents from December 1888 to May 1889. The palace was first called Istana Hinggap, Malay for "temporary", because Sultan Omar Ali Saifuddien III used it only when visiting Belait District.

Visiting the palace requires advance arrangements through official channels due to active security protocols and restricted visitor hours. Interested guests should contact relevant authorities ahead of time to make proper requests.

The building shifted between royal use and military housing within just a few decades after its completion. This dual function reflects the complex relationship between the Sultanate and British military presence in the region during that period.
