There exists in Vaishali, a pillar with a single lion capital erected by Ashoka.
The location of this pillar is contiguous to the site where a Buddhist monastery and a sacred coronation tank stood.
Excavations are still underway and several stupas suggesting a far flung campus for the monastery have been discovered. This pillar is different from the earlier Ashokan pillars because it has only one lion capital. The lion faces north, the direction Buddha took on his last voyage.
Identification of the site for excavation in 1969 was aided by the fact that this pillar still jutted out of the soil. More such pillars exist in this greater area but they are all devoid of the capital.
