This paper concerns the corrosion evaluation and protection study of metallic structural elements embedded in mortars and stone. The corrosion protection study of the metallic structural elements was evaluated at the Holy Aedicule monuments in Jerusalem. Chapel Aedicule, which contains the Holy Sepulchre itself, located in the center of Rotunda. The Aedicule has two rooms, the first holding the Angel’s Stone, which is believed to be a fragment of the large stone that sealed the tomb; the second is the tomb itself. In order to assess the environment and the corrosion rate of the metal components, visual inspection, corrosion potential of embedded metals (Open Circuit Potential) and the electrical conductivity of mortars and stones were measured. The aforementioned measurements resulted that the environment of the metal elements has low to moderate corrosive capacity. However, even if the corrosion environment is moderate, always in the case of monuments when metallic elements involved should be protected.

The study and the rehabilitation project of the Holy Aedicule became possible and were executed under the governance of His Beatitude Patriarch of Jerusalem, Theophilos III. The Common Agreement of the Status Quo Christian Communities provided the statutory framework for the execution of the project; His Paternity the Custos of the Holy Land, Archbishop Pierbattista Pizzaballa (until May 2016 – now the Apostolic Administrator of the Latin Patriarchate of Jerusalem), Fr. Francesco Patton (from June 2016), and His Beatitude the Armenian Patriarch of Jerusalem, Nourhan Manougian, authorized His Beatitude the Patriarch of Jerusalem, Theophilos III, and NTUA to perform this research and the project.
Contributions from all over the world secured the project’s funding. Worth noting Mica Ertegun’s and Jack Shear’s donations through WMF, Aegean Airlines et al.
The interdisciplinary NTUA team for the Protection of Monuments, Em. Korres, A. Georgopoulos, A. Moropoulou, C. Spyrakos, Ch. Mouzakis, were responsible for the rehabilitation project and A. Moropoulou, as Chief Scientific Supervisor, was responsible for its scientific supervision.
