Deterioration caused by long lasting and natural and human threats has exposed the historical fabric of cities and their unique values to irreparable damage. This paper aimed to investigate the factors threatened Tehran’s historical fabric. The study area has an area of about 1500 hectares and includes 21 neighborhoods. The data obtained from GIS data sets of 2016 Iranian Public Census, urban land use, worn-out fabric and zoning map of earth quake risk as well as two survey’s data set. Vulnerability is analyzed by 22 indicators. First, the data were analyzed qualitatively using descriptive statistical parameters, then they are integrated and entered into GIS to drive neighborhoods vulnerability map. Findings indicate a moderate level of vulnerability. Four neighborhoods that have the most important historical and heritage sites are among the most vulnerable neighborhoods. Also, central neighborhoods which are older and locate in Tehran business center district and encompass strategic political-governmental and economic centers are more vulnerable than the peripheral neighborhoods. Given that the least damage to cultural heritage and historical fabric is irreparable, even the smallest damage should be considered serious and action should be taken to protect the fabric from it. In conclusion, it is proposed to modify trade function, reorganize strategic centers and restore the function of housing in the Tehran historic fabric.
