Nalanda was an ancient center of higher learning in Bihar, India. The site is located about 88 kilometres south east of Patna, and was a religious center of learning from the fifth century AD to 1197 AD.Nalanda flourished between the reign of the sakraditya (whose identity is uncertain and who might have been either Kumara Gupta I or Kumara Gupta II) and 1197 AD, supported by patronage from the Hindu Gupta rulers as well as Buddhist emperors like Harsha and later emperors from the Pala Empire.The complex was built with red bricks and its ruins occupy an area of 14 hectares. (488 by 244 metres) At its peak, the university attracted scholars and students from as far away as Tibet, China, Greece, and Persia.Nalanda was ransacked and destroyed by an army under Bakhtiyar Khilji in 1193. The great library of Nalanda University was so vast that it is reported to have burned for three months after the invaders set fire to it, ransacked and destroyed the monasteries, and drove the monks from the site. In 2006, Singapore, China, India, Japan, and other nations, announced a proposed plan to restore and revive the ancient site as Nalanda International University.
