Agra, the only city in the world with three world heritage monuments to its credit, may soon receive the distinction of the world's only river front "heritage monuments club". A draft proposal for the formation of a heritage zone in Agra, clubbing the two world heritage monuments, Taj Mahal and Agra Fort, with two other contemporary river front monuments Itmad-ud-Daullah and Sikandra was passed recently at the UNESCO meet held in Durban.
