The Batu Tarsilah (Genealogical Stone Tablet) is a stone tablet listing the genealogy of Bruneian sultans from 1363 to 1804 CE, in addition to historical records such as Malay manuscripts and oral narratives. The Batu Tarsilah, a stone inscription dating back to 1807, documents Brunei's royal ancestry and was commissioned by Sultans Muhyiddin and Husin Kamaluddin. The tablet is regarded as the most trustworthy source for verifying Brunei's monarchy's ties to the Prophet Moḥammad's lineage (Ahl al-Bayt) and the Quraysh through comparative research based on Islamic genealogy, hence bolstering the legitimacy and sovereignty of Brunei's rulers. The historical and cultural grandeur of the sultanate is symbolised by this tablet.

The Royal Mausoleum (Malay: Kubah Makam Diraja) 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 history—particularly during the 19th and 20th centuries—and 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.
