Bandung is the capital of West Java province in Indonesia, and the country's third largest city, and 2nd largest metropolitan area in Indonesia, with 7.4 million in 2007. Located 768 m (2,520 ft) above sea level, Bandung has cooler temperatures year-around than most other Indonesian cities. The city lies in a river basin surrounded by volcanic mountains. This topography provides a good natural defense system, which was the primary reason for the Dutch East Indies government's plan to move the colony capital from Batavia to Bandung.
