Description & Facts: The Nag River, which is a tributary of the Kanhan River, flows in a serpentine path and so got its name, "Nag", the Marathi word for cobra. The river flows through the old city of Nagpur and so the city derived its name from this river, 'Nag'+'pur'. "Pur" is common suffix given to cities, villages and towns across India, and is often simply translated "city". The seal of Nagpur Municipal Corporation depicts a cobra in the water of a river. Nagpur is famous for growing oranges from which it derives it's nickname Orange city.
