Mar Saba Monastery

The Holy Lavra of Saint Sabbas, known in Arabic and Syriac as Mar Saba and historically as the Great Laura of Saint Sabas, is a Greek Orthodox monastery overlooking the Kidron Valley in the Bethlehem Governorate of Palestine, in the West Bank, at a point halfway between Bethlehem and the Dead Sea. The monks of Mar Saba and those of subsidiary houses are known as Sabaites.

Mar Saba is considered to be one of the oldest continuously inhabited monasteries in the world, and it maintains many of its ancient traditions. One in particular is the restriction on women entering the main compound. The only building that women can enter is the Women's Tower, near the main entrance.
