Kolkata, West Bengal

Kolkata, Bengali Kalikata, formerly Calcutta, is city in West Bengal and the former capital of British India (1772–1911). 
It is one of India’s most populous cities and major port. The city is centred on the east bank of the Hugli (Hooghly) River, once the main channel of the Ganges (Ganga) River, about 96 miles (154 km) upstream from the head of the Bay of Bengal; there the port city developed as a point of transshipment from water to land and from river to sea. Kolkata, the primary metropolitan centre of eastern India, is city of trade, transportation, and manufacturing.
