One of the major problems facing the old Cairo preservation efforts is that the older houses are being torn down and are replaced with modern apartment buildings. Such modern buildings are built with veyr little or no concern for the historical monuments existing in the area. As far as domestic architecture is concerned, the 'committee' that listed monuments to be saved has mentioned only few large houses as 'monuments to be saved'. (From the introduction to the article).
