For more than three thousand years, Bihar has been an important centre of human civilization in India. Centuries ago, students from all over the world used to come here to study at the ancient universities of Nalanda and Vikramshila. Currently, Bihar is making progress in reinventing itself in the areas of spiritual tourism and eco-tourism. A holy place for Hindus, Jain, Buddhists, and Sikhs alike, it attracts six million tourists every year.
