This study sheds light on the dynamic and static collapse causes of Ramses II pylon side by side an analytical study of the pylon construction system, causes such as, seismic loads, wind loads, the destruction of sandstone, by calculating the impact earthquakes and winds that have struck the pylon and relationship with construction stability also the impacts of bearing capacity, also the pressure force that generated by its loads over the foundation soil and relationship with infrastructure failure, a set of tests and analyzes were conducted on a deteriorated sample, the study found that the nubian earthquake force (27-28 BD) had led to a total failure of the upper half, with structural cracks, wind  loads incapable to collapse the pylon before earthquakes but in the current situation can affect and associated with the extreme material weakness of infrastructure and the inability of soil to bear the loads, found that wind loads above the foundation level £F=2,570 kn/m, and from foundation £M=44550 kn/m, current bearing capacity founded is equal to 91.8 kn/m2, not suitable for its-loads it was also found that earthquake loads on the pylon=437533.9 kn that demolished the pylon, and through sandstone testing showed low-coherent, presence of brown impurities, irregular extended and incoherence  molecules, foundation soil at 3-4 metres shows solid severity crystal with gaps, high smoothness mud, sandstone was analyzed, found (Quartz 89.8%, Kaolinite 8.9%, Halite 0.9%, Anatase 00.5) hence sandstone was deteriorated due to the agricultural waters adjacent to the pylon.
