Chittagong

Chittagong, officially Chattogram, is a major coastal city and financial centre in southeastern Bangladesh. The city had a population of more than 8.7 million in 2017, making it the second-largest city in the country. It is the capital and administrative seat of an eponymous District and Division. The city is located on the banks of the Karnaphuli River between the Chittagong Hill Tracts and the Bay of Bengal. Modern Chittagong is Bangladesh's second most significant urban centre after Dhaka.

Chittagong plays a vital role in the Bangladeshi economy. The Port of Chittagong, one of the world's oldest ports, whose coast appeared on Ptolemy's world map, is the principal maritime gateway to the country. The port is the busiest international seaport on the Bay of Bengal and the third busiest in South Asia.
