Patna is the capital of the Indian state of Bihar, and one of the oldest continuously inhabited places in the world. The Buddhist, Hindu and Jain pilgrim centres of Vaishali, Rajgir (or Rajgriha), Nalanda, Bodhgaya and Pawapuri are nearby and Patna is also a sacred city for Sikhs . Patna is located on the south bank of the Ganges River, called Ganga locally. Patna has a very long riverline, and it is surrounded on three sides by rivers—the Ganga, Sone, and Poonpun (also spelt Punpun). Just to the north of Patna across the river Ganga flows the river Gandak making it a unique place having four largish rivers in its vicinity.
