Geological appraisal of the Theban cliff overhanging the Hatshepsut temple at Deir el-Bahari

Summary/Abstract: Throughout its existence the Temple of Hatshepsut, as well as two other royal sanctuaries, the temples of Mentuhotep II and Thutmose III, located in the great bay of Deir el-Bahari, have been under constant threat of falling rocks from the overhanging Theban cliff. The PCMA UW archaeological expedition at Deir el-Bahari, which has progressed with the study and conservation of the Hatshepsut temple since the 1960s, has implemented a project designed to address the issue of the protection of the temple from damages that could be caused by environmental processes (rainwater and seismic activity) affecting the Theban cliff behind the monument. In a geological survey of the fractured limestone cliff, the evidence from 31 observation stations was appraised and samples of Esna Shale and Theban Limestone were examined in order to ascertain the degree of the cliff’s instability and fragility. The results were used to prepare a 2D model presenting the environmental processes threatening the ancient substance.
