<P> Vikramashila (village Antichak, district Bhagalpur, Bihar) is located at about 50 km east of Bhagalpur and about 13 km north - east of Kahalgaon, a railway station on Bhagalpur - Sahebganj section of Eastern Railway . It is approachable through 11 km long motorable road diverting from NH - 80 at Anadipur about 2 km from Kahalgaon . </P> <P> A number of monasteries grew up during the Pāla period in ancient Bengal and Magadha . According to Tibetan sources, five great Mahaviharas stood out: Vikramashila, the premier university of the era; Nalanda, past its prime but still illustrious, Somapura, Odantapura, and Jagaddala . The five monasteries formed a network; "all of them were under state supervision" and there existed "a system of co-ordination among them . It seems from the evidence that the different seats of Buddhist learning that functioned in eastern India under the Pāla were regarded together as forming a network, an interlinked group of institutions," and it was common for great scholars to move easily from position to position among them . </P> <P> Vikramashila was founded by Pāla king Dharmapala in the late 8th or early 9th century . It prospered for about four centuries before it was destroyed by Bakhtiyar Khilji along with the other major centres of Buddhism in India around 1200 . </P> <P> Vikramashila is known to us mainly through Tibetan sources, especially the writings of Tāranātha, the Tibetan monk historian of the 16th--17th centuries . </P>
