Stupa
Upon reaching Sindh instead of finding a Greek pillar Rakhal das actually found a Buddhist Stupa of the Kushana period which was supposedly constructed in 2nd and 3rd BC. Upon further excavations, in that area, Rakhal found the whereabouts of a 5000 year old city. This city which was named Mohenjo Daro along with Harappa proved the existence of the Indus Valley Civilization which was older than any European civilization.
