According Wikipedia : "By the end of 1949, and throughout the Jordanian occupation of the site, Arab residents uprooted tombstones and plowed the land in the cemeteries, while skeletons and bones were strewn about and scattered. An estimated 38,000 tombstones were smashed or damaged in total. Jewish tombstones from the Mount, both ancient and new, were used by the Jordanians for various purposes, including flooring for latrines and paving stones for roads. During this period, four roads were paved through the cemeteries, in the process destroying graves including those of famous persons. Buildings, including the Intercontinental Hotel and a gas station, were erected on top of ancient graves."
