What were the main features of the Vikramaśhilā University established by the Pālas?

Vikramaśhilā University, founded by Dharmapāla in the late 8th century, was a prestigious centre of learning with six colleges, monasteries, temples, lecture halls, and a vast library. Nearly 3,000 scholars studied subjects like grammar, logic, and philosophy. Each college had a dvārapaṇḍita ('scholar gatekeeper') who tested students before admission. The university had strong ties with Tibet and helped shape Tibetan Buddhism before being destroyed by Bakhtiyār Khiljī in the 12th century.
