Located at the foot of Mount Moses, St. Catherine's Monastery, was constructed by order of the Emperor Justinian between 527 and 565. It is built around what is thought to be Moses' Burning Bush, which has a chapel built atop it.
It is a spectacular natural setting for priceless works of art, including Arab mosaics, Greek and Russian icons, Western oil paintings, paintings on wax, fine sacerdotal ornaments, marbles, enamels, chalices, reliquaries, including one donated by Czar Alexander II in the 19th century, and another by Empress Catherine of Russia in the 17th century.
But of perhaps even greater significance is that it is one of the largest and most important collection of illuminated manuscripts in the world (The Vatican has the largest). The collection consists of some 4,500 volumes in Greek, Coptic, Arabic, Armenian, Hebrew, Slavic, Syriac, Georgian and other languages.
