It was first mentioned in history in 1000 and was the seat of the metropolitan of Jerusalem and was visited by many Syriac Orthodox Patriarchs. In 1235, it housed seventy monks. Four metropolitans graduated from it. In the fourteenth century it was usurped by a group of Muslims, with the help of the Mamluks; then it was converted it into a school called al-Maymuna. Its ruins were still standing until the 19th century, but it no longer exist.
