Most Armenian bishops live in monasteries. Etchmiadzin, the residence of the Catholikos of all Armenians, is the spiritual center of the Armenian Church. There is also a Catholicos of Cilicia, who resides in Antilyas in Lebanon, and leads the churches belonging to the Holy See of Cilicia. Since 1461 there has been an Armenian Patriarch of Constantinople. The Armenians possess the huge monastery of St. James, the centre of the Armenian Quarter of Jerusalem, where their Patriarch of Jerusalem lives, and the convent of Deir asseituni on Mount Zion with numerous nuns.
