The Chinese traveller, Hiuen Tsang, visited Nalanda and stayed for some time. He has given a detailed description of this place. There were stupas, chaityas, viharas, rest houses, steps here and there to sit and rest awhile, meditation rooms, lecture rooms, and many other structures reveal the glory of this place. The Gupta kings and Harshavardhana have been the famous patrons of this place. An accidental fire destroyed many texts at Nalanda.
