The deer park where Gautama Buddha first taught the Dharma is in Sarnath, and so the town is a major pilgrimage site. Within the deer park complex is a large stupa (Dhamekha Stupa) constructed by the Emperor Ashoka (2nd century B.C) and several other Buddhist structures that were added between the 3rd century BC and the 11th century AD.
