Abstract :
Reusing old materials was widespread in Ancient Egypt. Reusing building materials became a tradition in most cases for many reasons. Some can be economic reasons but others exceed this cause to become ideological reasons for reusing. This practice can be noticed in many areas in the lower parts of buildings or to hide the inscribed face of the block. On the other hand, there should be a degree of tension while reusing materials so, in addition to getting benefits from their ancestors and venerating them by reusing their material in later buildings, some kings sometimes were proud to surpass what their ancestors had done.
