Redevelopment of distressed and blighted areas are targeted by most of development policies. However, a number of policies have been changed as the result of the ineffectiveness of the previous experiences, the incompatibility of the development tools and plans, the lack of financial resources or social movements. Large-scale redevelopment projects have usually been considered as the powerful tools for urban revitalization, modernization and implementation of radical plans while many of those were criticized due to their various consequences including social exclusion, inequality, social conflicts, environmental damages, inconsistent scale, etc. Downtown of the City of Mashhad; Samen District, has experienced various physical interventions in the form of large-scale projects during the last century. Although the projects and intervention policies have been transformed during the past decades, previous faults were ignored and sometimes were iterated in these experiences. In fact, it seems that urban development solutions in the district have not been sustainable solutions and couldn’t maintain or shape a sustainable community in the historical and formerly economic urban core of Mashhad. This paper, focusing on mega redevelopment projects experienced in Samen Districst after 1920s, aims to highlight the critical aspects neglected or bent in Samen redevelopment program. Based on the nature of large-scale redevelopment projects and the current sustainability criteria, it qualitatively assesses the sustainability of the redevelopment projects through content-analysis method. According to the results, despite the competitiveness and place promotion goals of the Samen redevelopment project, the adopted approaches and policies could not lead to a state of sustainable development.
