(FILES) A part of an ancient column in the archeological site of Olympia stands in front of the charred ancient hill of Kronos, 24 November 2007. Greek and international scientists visited the World Heritage site to deliver funds for reconstruction of the area. A large replanting effort is under way ahead of March 25, when the flame-lighting ceremony for the Beijing Olympics will be held at the birthplace of the ancient games. Worsening wildfires, soaring heatwaves and rising water levels have prompted Greek officials to take a closer look at protecting priceless archaeological sites that draw hundreds of thousands of visitors each year. After a three-year from study by some of the country's leading scientific institutions, the Greek culture ministry has earmarked 19 monuments that most urgently need protection against natural threats, with several more to be bolstered by 2030.
