 The Mamluks also built the northwestern staircase and the six cenotaphs (for Isaac, Rebecca, Jacob, Leah, Abraham, and Sarah, respectively), distributed evenly throughout the enclosure.The Mamluks forbade Jews from entering the site, allowing them only as close as the fifth step on a staircase at the southeast, but after some time this was increased to the seventh step.During the Ottoman period, the dilapidated state of the patriarchs' tombs was restored to a semblance of sumptuous dignity.
