• Its wealth is on full display in its capital city, Bandar Seri Begawan, where oil money pays for glittering mosques and extravagant architecture.
• Much of the city's population lives in a floating village, where the houses, schools, and restaurants are all on stilts.

Brunei is one of the smallest countries in the world - at 2,200 square miles, it's smaller than Delaware, and its population is lower than that of Omaha, Nebraska.

Brunei's wealth is on full display in its capital city Bandar Seri Begawan, where grandiose mosques and extravagant buildings dominate the townscape and tributes to the country's mega-rich sultan lie around every corner.

But Brunei's capital is also a city of contrasts. Despite its flashy architecture, the streets of Bandar Seri Begawan are eerily quiet, and after dark, the lack of nightlife and bustle turns the mood downright surreal.

Even stranger, nearly half of the city's population lives in a floating village where houses, schools, restaurants, and police stations all rest on stilts in the middle of the Brunei River.
