found all around the country-side. This has led to the country itself being described an "open-air museum". George F. Taylor divided the temples of Lebanon into three groups, one group referred to the Temples of the Lebanese coastal plain to Mount Lebanon, another group as Temples of the Beqaa Valley and another area with a particularly heavy concentration was defined as the Temples of Mount Hermon. Damage to archaeological sites During the 2006 Lebanon war, a number of archaeological sites, including world heritage sites, were damaged as a result of Israeli aerial bombardments in Lebanon. A survey of the damage to sites in Lebanon was launched by UNESCO after the international archaeological community, including the director of the British Museum, Neil MacGregor, urged an investigation into the effects of bombing on "one of the planet's most heritage-rich countries." UNESCO's team of experts found that the most serious damage resulting from the conflict was at the world heritage site of Byblos, where an oil spill resulting from the targeting of fuel tanks at the Jiyeh power plant had stained the stones at the base of the port's two Medieval towers, among other archaeological remains on the seashore. Mounir Bouchenaki, Director-General of the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM) estimated that it would take twenty-five people eight to ten weeks to manually hand-clean the affected areas, placing the cost of the operation at some 100,000 USD. The mission also found that the main features of the world heritage site of Tyre, such as the Ancient Roman hippodrome and triumphal arch had escaped damage, but that frescoes in a Roman tomb at the site had come loose, likely because of vibrations caused by bombs. It was also reported that the world heritage site of Baalbek was not damaged by bombs, with the exception of the fall of one block of stone and the widening of fissures on the lintels in the temples of Jupiter and Bacchus, likely due to vibrations from nearby bombings. Also damaged by bombs, as noted by the mission, were the souk and some old houses in the Old City of Baalbek that were not part of the property inscribed on the World Heritage List. At a press conference revealing the results of the survey, Françoise Rivière, UNESCO's Assistant Director-General for Culture, reported on UNESCO's efforts during and after the fighting to
