Abstract: Almost all the Indian cities have a core area. The core areas are often high density, congested areas with very less open spaces. They have high concentration of population and are also linked with the strong heritage of the cities. These core areas are in the process of decay due to numerous reasons and this decay is now posing a threat to the heritage value of the cities. Of many reason for this decay is the fast changing lifestyle of the inhabitants of the place, changes in the economy of the people living in core areas, the neglect by the local developmental authorities and the lack of connection with the new developed areas of the cities. Often the core areas are bound by within the heritage zone and is separated from the new developed areas of the cities. The congested roads connecting the core areas make them in accessible for the people of the city.There is a strong need to connect the heritage core areas with the main city to save the rich heritage of such places for the future generations. The research paper tries to find a solution in mass transit rapid system in renewal and conservation of core areas.
