Authors of this article wish to collect previous research and broaden knowledge about limestone used for construction of the Temple of Hatshepsut and present results of the latest studies. The main purpose of the studies was to obtain information about tensile strength when bending architectural elements made of limestone. It will allow - among others - the span of architraves on which vault blocks, architrave and ceiling slabs with cornices and railings to be established, as well as their acceptable strength parameters. Theban limestone research most often focuses on the geological origin of this material and its microscopic analysis. These tests are supplemented by endurance tests necessary for the work of engineers and architects who work on the reconstruction or exhibition of the ancient temples. The authors of many years of work in Polish - Egyptian Archeology - Conservation Mission at the Temple of Hatshepsut at Deir el-Bahari solve everyday problems associated with exposure and reconstruction of the monument.
