Pataliputra, once the political and cultural center of India, has remained deserted since the Gupta decline in the mid-seventh century.
Sher Shah Sur, also known as Sher Khan or Lion King, the founder of the Sur Dynasty, has established his empire after conquering a huge swathe of territory that is now most of Afghanistan, Pakistan and northern India.
Refounding Pataliputra in 1541 as Patna, he envisions a fort and a town on the banks of the Ganga.
(Sher Shah's fort in Patna does not survive, but the mosque built in Afghan architectural style does.)
One of the oldest continuously inhabited places in the world, Patana is today a bustling city of 1,800,00 people, the capital of the Indian state of Bihar.
The Buddhist and Jain pilgrim centers of Vaishali, Rajgir or Rajgriha, Nalanda, Bodhgaya, and Pawapuri are all nearby.
Patna is a sacred city for Sikhs also, being the birthplace of the tenth and last "human" guru, Guru Gobind Singh.
