"[6] Istana Darul Hana, built alongside and facing the Brunei River,[7] was initially constructed using concrete and cement.

[10] Built in 1950 and completed in 1951 during the reign of Sultan Omar Ali Saifuddien III,[11] the palace became his official residence and office later that year, on 10 May.

Among these revived traditions were the awarding of honours in ceremonies held since 1954 and the royal wedding procession of Princess Norain and Pengiran Anak Mohammad Yusof in 1967.

[20] The sultan and his family were still at the palace on the night of the uprising, joined by a number of state dignitaries and six police officers.

[11] Later that year, on 29 July, the royal wedding of Crown Prince Hassanal Bolkiah and Pengiran Anak Saleha took place at the palace.

[11] On 7 May 1968, the sultan conferred the title of Pehin to Abbas Al-Sufri, followed by further honours to Isa Ibrahim and Haji Awang Jair bin Ja'afar later that month.
