Chandraketugarh, located in the Ganges Delta, are a cluster of villages in the 24 Parganas district of West Bengal, about 35 kilometres (22 mi) north-east of Kolkata. The name Chandraketugarh comes from a local legend of a medieval king of this name. This civilization can perhaps be identified with the Gangaridai of Graeco-Roman accounts. In early historic times, Chandraketugarh was connected to the Ganga by the Bidyadhari River and must have been an important centre of trade and possibly also a political centre.
