Giza plateau in Egypt is famous for its pyramids and tombs which were built and carved into the rock. The pyramid of Queen Hetep Heres, the mother of King Khufu, encountered several erosion factors. From a simple visual examination, it is noted that Hetep Heres' pyramid has many problems that affect its sustainability. Different samples have been taken from the eroded areas. The external state that was investigated by a stereo microscope shows erosion and damage. The internal and structural states were investigated by scanning electron microscope, X-ray diffraction, EDAX, and laser-based Raman microscope. This study confirms the need to interfere with the surrounding urban area to decrease the frictions and the strong need to continue developing the Giza Plateau to decrease the environmental effects on the whole archeological buildings found in one of the most important plateaus in the world.
