Imagine a building whose size exceeds the Vatican and Buckingham Palace combined. This is exactly what Istana Nurul Iman, or the "Palace of the Light of Faith," looks like—the official residence of the Sultan, located in the city of Bandar Seri Begawan. It is not just the monarch's home, but also the active center of government for Brunei, listed in the Guinness World Records as the world's largest residential palace for a head of state.

Spanning an area of about 120 hectares on a picturesque riverbank, the palace is staggering in its scale: it features 1,788 rooms, over 250 bathrooms, its own mosque, and a massive underground garage. The architecture of the complex is a harmonious blend of contemporary style and traditional Islamic motifs, topped with a magnificent golden dome that is visible from afar.
Inside lies a true treasury: from a banquet hall for 5,000 guests to a collection of priceless paintings by famous artists such as Renoir. Istana Nurul Iman embodies the wealth and grandeur of the Bruneian monarchy while remaining an important symbol of the people's spiritual unity.
