The Grave of Awang Haji Besar bin Awang Sagap@ Pengiran Ibrahim bin Pengiran Sagap (21 September 1914 – 1988) located at the compund of the Royal Mausoleum Kubah Makam Diraja Jalan Tutong, Bandar Seri Begawan.
Awang Haji Besar bin Awang Sagap@ Pengiran Ibrahim bin Pengiran Sagap was a prominent Bruneian composer and musician, best known for his contribution to Brunei's national anthem, "Allah Peliharakan Sultan".
At the time of the anthem's creation, Awang Besar was employed by the Public Works Department under the British Military Administration.
In 1947, a group of young Bruneians initiated the movement for a national anthem, inspired by similar developments in other nations. This led to the selection of Awang Besar and Pengiran Muhammad Yusuf to create the piece; Awang Besar composed the music, while Pengiran Muhammad Yusuf penned the lyrics.
The song gained traction after being performed by members of the Barisan Pemuda (Youth Front) during their first anniversary celebration on April 12, 1947. After undergoing several revisions and being taught in Malay schools in Brunei Town, "Allah Peliharakan Sultan" was officially adopted as the national anthem in 1951, following the coronation of Sultan Omar Ali Saifuddien III in 1950.
