Varanasi (Benares, Kashi) is the oldest living city in the world. It is the most sought after pilgrimage town for Hindus. It is believed, if anyone dies in Varanasi they attain salvation and freedom from the cycle of birth and rebirth. Sarnath, just 10 km away, where Buddha preached his first sermon after enlightenment, attracts devotees of many faiths. It is also a centre of knowledge.
