The transitions from tradition to modernity has occurred when the Industrial Revolution imposed fundamental changes in different aspects of our civilizations. From this historic period, a valuable heritage has survived, such as first factory buildings that contain valuable information for today s studies. These factories, which are now largely ruined and abandoned, have high potential and much strength that make it necessary to protect even if the restoration and regeneration are beyond commercial senses. This research, which is a historical-theoretical research, investigates a number of regeneration projects of historical factories outside and inside Iran through a literature review. Historical factories of Iran are categorized according to the ideology, style and purpose of construction of the three Qajars, Pahlavi I, Pahlavi II and after the Islamic Revolution. Finally, by analyzing and reviewing scientific literature, reports on subjective meetings related to industrial heritage, and the experts’ opinion in this field, the requirements’ definitions and preservation methods and regeneration of Iranian historical factories comes to light.
