The Holy Lavra of Saint Sabbas (Greek: Ἱερὰ Λαύρα τοῦ Ὁσίου Σάββα τοῦ Ἡγιασμένου, romanized: Yerá Lávra tú Osíu Sávva tú Iyazménu), known in Arabic and Syriac as Mar Saba (Syriac: ܕܝܪܐ ܕܡܪܝ ܣܒܐ, romanized: Dayrā d-Mār Sabba; Levantine Arabic: دير مار سابا, romanized: Dēr Mār Sābā; ) and historically as the Great Laura of Saint Sabas, is a Greek Orthodox Christian 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 one of the world's oldest (almost) continuously inhabited monasteries, and it maintains many of its ancient traditions. One in particular is the restriction on women entering the main compound. The only building women can enter is the Women's Tower, near the main entrance.
