Despite the lingering debt crisis in Greece over the past few years, the restoration and protection of the Acropolis hill has never ceased, partially due to the funds they receive from both Greek government and the European Union. Since 1975, the total cost of the restoration works on the Acropolis hill stands at 100 million euros (109.02 million U.S. dollars), according to Vassiliki Eleftheriou, director of the Acropolis Restoration Service. Considering the size of the project, the amount was small, she said. Eleftheriou is in charge of the operation and spoke recently about future plans for the massive undertaking.

 "Funding has never been a major problem. The Greek state always supported us. This is a national treasure and its protection is a national goal, a matter of national priority."

Standing on the hill, Eleftheriou said restoration of the cultural relics has always been a difficult and delicate task for her agency. Eleftheriou and her colleagues have to move forward with their restoration and maintenance work while keeping the Acropolis hill open to thousands of tourists every day.

Work at an open archaeological site does not progress at a very fast pace. Reporters at the scene saw only two cranes operating on site while archaeologists and craftsmen were confined to a small corner near the hill's entrance to do their job.

Comprised of experts who have won international acknowledgment for their work, the Acropolis Restoration Service was set up with the aim of preserving the masterpieces constructed in the 5th century BC. As technology advances, the service is constantly seeking the best materials, tools and techniques to reverse the damage caused by time, environmental pollution and the human factor, according to Eleftheriou.

To maintain the structural integrity and authenticity of the monuments, archaeologists are careful with the decisions and materials they use. Before any decision to restore the relics is made, a multidisciplinary committee of scholars will examine the proposal submitted by archaeologists, architects and other specialists.

To stabilize the monuments and address static problems, for example, Greek experts used titanium to reinforce broken stones in the past four decades. The use of the latest technological tools such as 3D filming is also helping Greek experts and officials to document the site with more accuracy for further scientific research as well as bringing it closer to wider audiences. Only the best materials are used. For example, the white marble used for completing the eroded architectural elements is quarried from the same mountain as the antiquity.

The Acropolis Restoration Service is also seeking wider and deeper collaboration with other countries, including China, on the know-how of antiquity protection. Eleftheriou believes this is an efficient way to ensure the Acropolis monumental ensemble is better protected and passed down to future generations.
