The historical place at which the Enlightenment took place became a place of pilgrimage. Though it is not mentioned in the scriptures, the Buddha must have visited Bodh Gaya again in the course of his teaching career. About 250 years after the Enlightenment, the Buddhist Emperor, Ashoka visited the site and is considered the founder of the Mahabodhi Temple.

According to the tradition, Ashoka, as well as establishing a monastery, erected a diamond throne shrine at this spot with a canopy supported by four pillars over a stone representation of the Vajrasana, the Seat of Enlightenment.

The temple's architecture is superb but its history is shrouded in obscurity. It was constructed with the main intention of making it a monument and not a receptacle for the relics of the Buddha. Several shrines were constructed with enshrined images for use as places of worship.

The basement of the present temple is 15m square, 15m in length as well as in breadth and its height is 52m which rises in the form of a slender pyramid tapering off from a square platform. On its four corners four towers gracefully rise to some height. The whole architectural plan gives pose and balance to the observers.

Inside the temple there is a colossal image of the Buddha in the "touching the ground pose", bhumisparsha mudra. This image is said to be 1700 years old and is facing east exactly at the place where the Buddha in meditation with his back to the Bodhi tree was enlightened.
