One of the most sacred places for Buddhists, the temple is an imposing example of early brick structures in India. It holds the diamond throne, a colossal image of Buddha and the holy Bodhi tree.
The temple stands in the east to the Bodhi Tree. Its architectural effect is superb. Its basement is 48 square feet and it rises in the form of a slender Pyramid till it reaches its neck, which is cylindrical in shape. The total height of the temple is 170 ft. and on the top of the temple are Chatras which symbolize sovereignty of religion. Four towers on its corners rise gracefully giving the holy structure a poise balance. This sacred edifice is like a grand banner unfurled by time to proclaim to the world the pious efforts of the Buddha to solve the knots of human miseries, to ascend above worldly problems and to attain transcendental peace through wisdom, good conduct and disciplined life.
Inside the temple, in the main sanctum, there is a colossal image of theBuddha in sitting posture touching the earth by his right hand. In this posture the Buddha accomplished the supreme enlightenment. The statue is of black stone but it has been guilder by the devotees. The entire courtyard of the temple is studded with large number of votive stupas. These stupas are of all sizes built during the past 2500 years ago. Most of them are extremely elegant in structural beauty. The ancient railings, which surround the temple, are of the first century BC and are among the very interesting monuments of the century.
