Bandar Seri Begawan, the largest city in Brunei with about 100,000 people, is the country’s capital located in Southeast Asia’s Borneo Island, renowned for its stunning mosques and cultural landmarks. Among them, the Sultan Omar Ali Saifuddien Mosque stands out with its golden dome and lagoon that encircles the primary structure, making it a popular spot for both locals and visitors.

The Royal Regalia Museum and the Brunei History Centre are noteworthy landmarks in Bandar Seri Begawan that exhibit Brunei’s historical and cultural heritage. Another must-visit attraction is the Kampong Ayer water village, a cluster of stilted homes and shops on water with a rich history, making it one of Brunei’s most distinct cultural spots.
