Assandh in the Karnal district of Haryana has for long been in the shadows of better known Buddhist sites.  The place has the unique distinction of being home to an imposing Buddhist Stupa. With a height of 25 metres and diameter of 75 metres, this colossal structure testifies to the greatness of the ancient Buddhist architecture.
The probable date of the establishment of the Assandh stupa is ascribed to the Kushana period (1st-3rd century AD). Kanishka, the greatest of the Kushanas, was a great patron of Buddhism. Several remains bear testimony to the popularity of Buddhism during his reign. The Mathura school of art which is credited with having produced the first images of the Buddha flourished under the Kushana rule.
