This chapter provides an overview of Tehran’s urban development and shows how the city’s growth has been influenced by natural settings, cultural ideals, and economic and political processes. I explain the class structure of the city (moving from the north to the south, one perceives a gradual shift from wealthier neighborhoods to poorer ones) and its historical and geographical evolution. With an emphasis on grand urban visions, I discuss how natural, historical, and political forces have contributed to the unequal structure of the city.
