In order to maintain the old historical image of the city, it is necessary to look back into the past and identify the iconic buildings that have been existing during the last decades. By recognizing those valuable structures, architects together with the help of decision makers should take actions to revitalize the uses of those valuable buildings in order to prevent building’s decay or destruction. Old historical Arabic public bathhouses (Hammam) were chosen as distinctive buildings that have been used frequently during the 19th century in Alexandria city. The main objective of this paper is to highlight the importance of applying the rehabilitation policies for the revitalization of those heritage buildings that have shaped for a long time the character of the old town in Alexandria. This paper will first discuss the beneficial use of the rehabilitation scheme that helps in safeguarding the social, cultural and economical value of the built heritage. The concept of rehabilitation mainly focuses that no historic building should be pulled down until serious effort has been made.
