Colosseum leaning? Repair date for December

3 of 7: A technician controls how far fragments from a stone dropped from the top of Rome's ancient Colosseum spread, to evaluate possible risks to visitors, Wednesday, July 18, 2012. Colosseum director Rossella Rea said the test are being done to evaluate the eventual need of new safety measures in case of an accidental fall of rocks from the monument. She also said that the recent climate changes, with unusually heavy rains, snowfalls and extreme temperatures are causing micro deterioration that could ease the release of stone fragments.
