Brunei is a small, oil-rich sultanate on Borneo's northern coast, one of the world's wealthiest nations where citizens pay no income tax and enjoy subsidized housing, education, and healthcare. The Sultan's golden-domed Omar Ali Saifuddien Mosque is among Asia's most beautiful, while the Istana Nurul Iman palace is the world's largest residential palace. The capital Bandar Seri Begawan includes Kampong Ayer, a water village of 30,000 people connected by walkways and boats. Rainforest covers over 70% of the country, with Ulu Temburong National Park offering canopy walkways and pristine jungle. Brunei blends Islamic tradition with oil-funded modernity, offering a glimpse of a unique governance model rarely seen by visitors.
