How the world's oldest university was lost for 800 years

Founded more than 1,500 years ago, India's ancient Nalanda University is thought to have been the world's first residential university.

Established more than 500 years before Oxford University, at its peak Nalanda hosted over 10,000 students from around the globe. It is considered by historians to be one of the great centres of learning of the ancient world.

The university was destroyed towards the end of the 12th Century AD. Its legendary library burned to the ground and much of its ancient knowledge was lost.

Now, 800 years later, the university is being revived for the modern age.
