capital of Brunei. The city lies along the Brunei River near its mouth on Brunei Bay, an inlet of the South China Sea on the northern coast of the island of Borneo. Bandar Seri Begawan was once predominantly an agricultural trade centre and river port. After suffering extensive damage during World War II, it was largely rebuilt and became the country's administrative and financial centre, with a port at the nearby mouth of the Muara River. Notable buildings include the Istana Nurul Iman (the royal palace), the Hassanal Bolkiah National Stadium, and the Sultan Omar Ali Saifuddien Mosque, which is among the largest mosques in Southeast Asia. Located on the main road running southwestward along Borneo's coast to Seria and Kuala Belait, Bandar Seri Begawan is home to Brunei's only international airport. It also has ferry terminals offering service to neighbouring ports. Pop. (2001) city, 27,285; (2004 est.) urban area, 81,500.
