In Sarnath, Buddha preached his first sermon to his followers. Right after he attained Nirvana under a Bodhi Tree in Bodh Gaya, he traveled to Sarnath to preach. That sermon he gave became the central belief of Buddhism: The Four Noble Truths and the Eight-fold Path. Today, Sarnath is synonymous to Siddhartha Gautama Buddha. There’s a humongous stupa in the place where he used to sit and preach. This stupa is the most preserved in the area and it towers over the land where temples once stood. The surrounding area still carries the ruins of the Buddhist Temples of ancient yore.
