The most amazing thing about Israel is the Me'arat HaMachpela.
Factoid: The Cave of Machpela (the Tomb of the Patriarchs) is located in the ancient city of Hebron. The site is the burial place of three Biblical couples: Abraham and Sarah; Isaac and Rebekah; Jacob and Leah. According to Midrash and other sources the Cave of the Patriarchs also contains the head of Esau.
