In the English language; a buffer zone is an area that separates two other areas. In this research, we hint to the main role of a buffer zone in preserving heritage with universal value through organizing the means of dealing with the surroundings of its historic area. For example, the visual impact of high rise buildings within the buffer zone needs to be considered; as well as the reflection of legislations and rules of management on the borders and boundaries of the site. This is in addition to the pressure of urban development, and the most stressing problem; the land use between sole heritage and combatable activities; while these activities may be welcome to the site when suiting the value of cultural heritage. To insure the protection of the heritage site, unplanned tourism of the surroundings should be eliminated. If a buffer zone is considered a means of protection for the site, then it was mainly meant to be a management tool. It's supposed to be a first defense line in front of the heritage site to make sure the management plan is effectively implemented. Heritage values should be stated in order to clarify which activities happening in the buffer zone may harm the heritage values, so as to avoid them; especially when these activities might destroy the built fabric. We need to make it clear what is allowed and what is not. However, a problem may strongly arise if the buffer zone is not stated on the national law of its country; as in the case here; in Egypt. If the buffer was meant to act like as means of protection, it already needs to be protected in the first place to perform its duty. In this research, the experimental approach is adopted through cluster analysis in addition to logistic regression. The final outcome of this research is an assessment of buffer zones by arranging priorities of intervention
