Architectural Grandeur and the Scale of Modern Monarchy
Completed in 1984 at an estimated cost of $1.4 billion, the massive structure spans over 2.15 million square feet (200,000 square meters). Designed by renowned Filipino architect Leandro V. Locsin, the complex seamlessly blends traditional Islamic architecture with Malay royal design, topped by dramatic vaulted roofs and soaring golden domes. The interior, crafted by designer Khuan Chew, incorporates fine Italian marble, Chinese silk, and extensive 22-karat gold leaf detailing.
The interior features unprecedented scale and functional luxury:
- 1,788 rooms and 257 bathrooms dedicated to state and personal affairs.
- A grand banquet hall capable of hosting up to 5,000 guests simultaneously.
- An internal mosque accommodating up to 1,500 worshipers.
- Air-conditioned stables built for over 200 polo ponies alongside an expansive garage housing a historic luxury vehicle collection.
Public Access and the Iconic Hari Raya Tradition
While the Sultan of Brunei palace functions primarily as a high-security state residence and administrative capital, it opens its doors to the public during the annual celebration of Hari Raya Aidilfitri. For three consecutive days following the holy month of Ramadan, tens of thousands of local citizens and international tourists pass through the palace gates.
During this annual open house event:
- Visitors receive complimentary festive meals served inside the palace's grand dining halls.
- Guests participate in direct royal greetings with the Sultan and senior members of the royal family.
- Children and visitors are presented with traditional green packet gifts and commemorative mementos directly from the royal household.
