There was a time when the river flowed in between the historical buildings, Red Fort on one side and Salimgarh Fort on the other and at present the scenery have changed. Not only the scenery but also the water of the river. The river was used for farming purposes and many more basic chores of household but now Yamuna has turned into one of the most polluted rivers in the country.
