 At the center of the northeastern side, there is another entrance, which enters the roofed area on the southeastern side of the northwestern section and through which access can also be gained to the southeastern (fully roofed) section.This entrance is approached on the outside by a corridor which leads from a long staircase running most of the length of the northwestern side.The southeastern section, which functions primarily as a mosque, contains two cenotaphs, symmetrically placed, near the center, dedicated to Isaac and Rebecca.
