This ancient kingdom and port city was bounded by the Bay of Bengal in the south, Rupnarayan River in the east and Subarnarekha River in the west. The Rupnarayana is the joint flow of the rivers Dwarakeswar and Silai. The Bay of Bengal and these great rivers with their numerous branches created a prosperous and easy water navigational system fostering commerce, culture and early contacts with the people outside the region. At the same time, these rivers helped to develop the agriculture in this region.
