Rajgir, meaning the abode of Kings, has been mentioned first in the ancient Hindu epic Mahabharata as the capital of Magadh, ruled by the mighty King Jarasandha. Although the exact time of the origin of this city has not been established, it is estimated by scholars that it must be around 3,000 years old. Rajgir has been mentioned in ancient Buddhist and Jain scriptures and also in the travelogues of Buddhist travellers Huen Tsang and Fa Hian who visited India during the Mauryan and Gupta times. The city is divided in two parts, the old fortified city which lies in the valley surrounded by seven hills (Chhatha, Ratna, Saila, Sona, Udaya, Vaibhara and Vipula) and the new city established by Ajatshatru, the son of Bimbisara and a contemporary of Lord Buddha. Rajgir has been closely related to Hinduism, Buddhism and Jainism and has played host to Lord Buddha and Mahavira, thus has many archeolgical sites related to Buddhism and Jainism.
