An extended restoration program of the Athenian Acropolis monuments has been in progress since 1975. The project is carried out by the Hellenic Ministry of Education and Religious Affairs, Culture and Sports in order to alleviate the effects of serious problems due to natural causes (i.e. earthquakes) or human activities (i.e. fires, bombardments or earlier restorations). The interventions are complied with the spirit of the “Charter of Venice” and follow the principle of reversibility. Effort focuses on keeping the original construction form of the monuments. New marble is used for supplements only to ensure the structural stability of the buildings, while iron clamps and dowels are being replaced by reinforcements made of titanium. The authentic reliefs and sculptures are removed and transferred to the Acropolis Museum and replaced by casts in artificial stone. Scattered architectural fragments recognized as belonging to the monuments are reset in their original or a corresponding position. The paper focuses on the recent intervention programs on the projects underway at the Propylaia and the Parthenon.
