Long shot of Sanchi Stupa # 1, Sanchi, Madhya Pradesh, India. The stupa was vandalized at one point, sometime in the second century BCE, an event some have related to the rise of the Sunga emperor Pusyamitra Sunga. It has been suggested that Pushyamitra may have destroyed the original stupa, and his son Agnimitra rebuilt it.[2] During the later rule of the Sunga, the stupa was expanded with stone slabs to almost twice its original size. The dome was flattened near the top and crowned by three superimposed parasols within a square railing. With its many tiers it was a symbol of the dharma, the Wheel of the Law. The dome was set on a high circular drum meant for circumambulation, which could be accessed via a double staircase. A second stone pathway at ground level was enclosed by a stone balustrade with four monumental gateways (toranas) facing the cardinal directions. The buildings which seem to have been commissioned during the rule of the Sungas are the Second and Third stupas (but not the highly decorated gateways, which are from the following Satavahana period, as known from inscriptions), and the ground balustrade and stone casing of the Great Stupa.
