The Hall of Isaac including the entrance to the Garden of Eden is open for Jews 10 times a year.
The Tomb of Machpela is the 2,000-year-old structure that covers the underground cave of the Patriarchs and Matriarchs. It contains both a synagogue area and a mosque area with each side being managed separately with separate entrances.
For ten days a year, the Muslim area of the Tomb of the Patriarchs is open for Jewish prayer services and for another ten days, the Jewish area is open for Muslim prayer services. This gives each side free access to otherwise off-limits sections, although certain sections are off limits even during these special days.
During normal days, the complex is divided into Jewish and Muslim areas with the Hall of Isaac and Rebecca reserved for Muslim prayers. This hall contains the small opening into the underground caves, known as the “entrance to the Garden of Eden.”
