The 300 tombs are gouged out of the rock, all unpainted tombs except for two. The paintings had been damaged by the humidity caused by visitors' breath, and cracks were showing on its walls so that some parts of the paintings had even become detached from the base rock. Both tombs were closed in 1992 and several attempts were made to restore and consolidate them. Early this month the Supreme Council of Antiquities (SCA) began a comprehensive project to rescue the tombs.
