A.S.I. Excavation
Location : Google Maps
The present city, which appears to be situated on a hill of a height varying from 7 to 30 meters, is actually sitting on a very large artificial mound. This mound is created by a number of layers of buildings built and destroyed in earlier periods. Diggings done for archaeological excavations or construction of houses in recent times show no end to these layers till one reaches to the level of farmland surrounding the city. Source
