Egypt’s palaces have various openings and architectures, the most significant of which were
those openings containing stained glass. Due to the degradation of most stained-glass
windows in the Egyptian palaces that are full of artistic works of high production quality and
the increase of degradation factors, whether natural or artificial, they should be immediate
conserved to keep this heritage from extinction. Thus, the study investigates, diagnoses, interprets
the degradation phenomena of stained glass in some Cairo palaces from 1850 to 1950. It also
investigates their relation to the internal degradation of most glass pieces. Furthermore,
damage caused by humans due to negligence and ignorance of handling this type of monuments
is studied. It proposes a plan of a national project to restore and maintain this heritage. Therefore,
it utilizes the descriptive and analytical approach besides the comparative one to define and
present degradation manifestations of stained glass in Sakakini palace (est. 1897), Prince
Youssef Kamal Palace (est. 1908), Tahra palace (est. 1915), and Rustom pasha palace (est.
1927). The study recommends paying special interest to those windows and setting a national
project to restore those palaces, in general, and their stained-glass, in particular.
