Bandung (/ˈbɑːndʊŋ/) (formerly Dutch: Stad Bandoeng, Sundanese: ᮘᮔ᮪ᮓᮥᮀ, Indonesian: Kota Bandung), is the capital of West Java province in Indonesia and Greater Bandung made up of 2 municipalities and 38 districts, making it Indonesia's 2nd largest metropolitan area with 8,495,928 inhabitants listed in the 2015 Badan Pusat Statistik data. It is the nation's third most populous city, with over 2.6 million (2015). Located 768 metres (2,520 feet) above sea level, approximately 140 kilometres (87 miles) south east of Jakarta, Bandung has cooler year-round temperatures than most other Indonesian cities. The city lies on a river basin surrounded by volcanic mountains. This topography provides a natural defense system, which was the primary reason for the Dutch East Indies government's plan to move the colony capital from Batavia (modern-day Jakarta) to Bandung.
