The Royal Mausoleum () in Batu Satu, Bandar Seri Begawan, is a significant historical and cultural landmark in Brunei. Located along the Brunei River, it lies beyond Kampong Ayer and on the route from Bandar Seri Begawan to the Istana Nurul Iman. This site serves as the final resting place for several Bruneian sultans and members of the royal family, with Sultan Omar Ali Saifuddin I, who died in 1795, being the first monarch interred here.
Although the mausoleum holds immense significance in Brunei's monarchical historyâÂÂparticularly during the 19th and 20th centuriesâÂÂand in its interactions with the British, it remains relatively off the main tourist trail and is less visited by foreign tourists. Despite this, it is a notable destination for domestic visitors, offering a peaceful setting with ample parking and a refreshment shop for convenience.
The graves of several Brunei sultans are designated as ancient monuments and historical sites under the Antiquities and Treasure Trove (Ancient Monuments and Historical Sites) Order, 2007. Sultan Omar Ali Saifuddin I is among the earliest recognised rulers, buried at Makam Besar, Makam Diraja. Other sultans interred at Makam Damit, Makam Diraja include Sultan Muhammad Tajuddin, Sultan Muhammad Kanzul Alam, Sultan Muhammad Jamalul Alam I, and Sultan Omar Ali Saifuddin II. Later monarchs are buried inside the mausoleum, such as Sultan Hashim Jalilul Alam Aqamaddin, Sultan Muhammad Jamalul Alam II, Sultan Ahmad Tajuddin, and Sultan Omar Ali Saifuddien III. Meanwhile, the alleged tomb of Sultan Abdul Momin is not gazetted in the order.
