This chapter reveals the history of urban conservation in Historic Cairo and the roles of key players, specifically critics. In general, it is necessary to criticize the efforts of conservation, yet it is significant that almost none of the articles investigated the experience through a post-operative methodology. Despite the massive local literature produced through newspapers and scientific magazines, no empirical methodology with definite examination criteria was implemented to evaluate any of the interventions of urban conservation. Urban conservation in Egypt is still heeding philosophical criticism based on intellectual knowledge and background. However, because there are enormous funds available to preserve and conserve, the time has come to apply new assessment methods of evaluation toward the urban interventions at historic sites. There are various approaches that assess the interventions of developing Historic Cairo. Such objective approaches will give space to add other substantial factors within the assessment approach rather than philosophical or theoretical judgements.
