Nalanda, a very old buddhist monastry, is also considered by some historians as a university. It is believed that Nalanda was a place where many learned scholars met and exchanged ideas. Recent excavations by the Archeological Survey of India have shown that at its peak, several thousands of students lived and studied at this place. This monastery was burnt and ransacked by a muslim ruler, Bakhtiyar Khilji. What are left today are the ruins of the Nalanda University.
