18. Temburong (Brunei in Malaysia)
Temburong is a unique exclave of Brunei, divided from the main part of the country by Malaysian territory. Historically carved out by colonial-era boundary agreements, Temburong is accessible either by crossing through Malaysia or via the impressive Sultan Haji Omar Ali Saifuddien Bridge. This separation shapes everything from daily commutes to the delivery of services. Temburong’s existence vividly demonstrates how the legacy of colonial borders continues to influence national geography and connectivity across Southeast Asia.
