Istana Nurul Iman

The name "Istana Nurul Iman" is taken from Malay Istana and Arabic Nur-ol Imaan and means Palace of the Light of Faith. It was designed by Filipino Visayan architect Leandro V. Locsin, who utilized the architectural motif of golden domes and vaulted roofs to echo Brunei's Islamic and Malay influences. The interior of the palace was designed by Khuan Chew, Design Principal of KCA International, whose other works include the Burj Al Arab in Dubai. Construction was handled by Ayala Abbott and Butters, a UK construction firm, and completed in 1984 at a total cost of around US$1.4 billion.

The title of the "world's largest palace" is difficult to ascertain, and controversial, as different countries use their own unique standard to claim that their palace is the largest. Using various definitions, a number of palaces are claimed to be the world’s largest: Istana Nurul Iman, Buckingham Palace, Quirinal Palace, Royal Palace of Madrid, Stockholm Palace, The Forbidden City, The Palace of Versailles, The Royal Palace of Caserta, The Winter Palace, The Louvre Palace, Prague Castle, The Grand Palace and The Palace of the Parliament.

To be considered for the Guinness World Record, the palace must have been intended for use as a royal residence, and only the combined area of the palace’s indoor floors (a measurement commonly known as floorspace) is considered. As measured by these standards, Guinness World Records currently considers Istana Nurul Iman to hold the title as the "world's largest residential palace."[2] Upon completion, Istana Nurul Iman became the largest residential palace in the world and the largest single-family residence ever built.[3] The palace contains 1,788 rooms, which includes 257 bathrooms, a banquet hall that can be expanded to accommodate up to 5,000 guests, a mosque accommodating 1,500 people.[4] The palace also includes a 110-car garage, an air conditioned stable for the Sultan's 200 polo ponies, and five swimming pools. In total, Istana Nurul Iman contains 2,152,782 square feet (200,000 m²) of floorspace.[4] Istana Nurul Iman has 564 chandeliers, 51,000 light bulbs, 44 stairwells and 18 elevators.[4]

The Sultan takes his official audiences at the palace. The palace is also used for all the state functions of the government of Brunei. In addition, the palace houses the prime minister's office, and serves as the seat of the Brunei government.

In addition to audience and state rooms, there is a throne chamber used for various formal occasions such as the proclamation of the crown prince and the annual birthday investiture.

However, in keeping with its primary use as the Sultan’s personal residence, the palace is the home to the Sultan’s 7,000 cars in 110 separate garages. The cars are valued at around $5 billion.[5]

The palace is not open to the public except on the annual Islamic celebration of Eid-ul-Fitr (the festival at the end of the Muslim fasting month) when the palace receives about 110,000 visitors over a three-day period where the guests receive gifts of food as well as green packets containing money for young children. The palace is also open to Muslims during 10 days of the Ramadhan period for Tadarus and Tarawih prayer gathering.
