Saint Catherine's Monastery, Egypt

The Sinai Monastery of St. Catherine was built at the foot of Mount Sinai in Egypt by Emperor Justinian I between 527 and 565. 
This mountain is revered equally by Jews, Christians and Muslims as the place where Moses received the Ten Commandments. This is probably the oldest monastery in history, which has never ceased to perform religious services and is still active today. 
According to legend, here Moses sees the burning bush, God's sign and the announcement that he was chosen as a prophet. It has been declared a UNESCO World Heritage Site.
St. Catherine's Monastery has the library with the largest collection of manuscripts after the Vatican Library, as it boasts over 2,000 icons. 
Before the monastery of St. Catherine was built, a chapel was built on this place, created in the IV century by Empress Elena. As the place became a haven for many pilgrims, Justinian built a fortified monastery to protect monks and pilgrims from invaders. 
Many years passed before the monastery was dedicated to the early Christian saint St. Catherine, who was proclaimed a great martyr in the IV century. She is crucified on a wheel, which falls apart after she touches it, causing her to be beheaded.
According to the legend angels tooked her body and hid it so that it could be found intact six centuries later by monks on Mount Sinai. The only building in the monastery that is open for visits is the Basilica of the Transfiguration or the Church of St. Catherine. It is worth visiting because of the magnificent icons arranged in the vestibule of the temple.
The library of the St. Catherine's monastery has the second most important collection of religious manuscripts. It is strictly guarded, as they are very valuable documents, namely one of the rarest manuscripts - the Sinai Codex, disappeared after a German scholar borrowed it. Today this document is in the possession of the British Library.
You must visit the Well of Moses, which marks the place where the ancestor met all the other wives of Sephora. Nearby is a grafting shrub surrounded by a wooden lattice, which was originally considered a burning shrub. The uniqueness of the monastery is enhanced by the mosque built opposite the entrance to the basilica. It was built for the only Bedouin working for the monks. It is believed that she was the one who stopped the monks from being attacked by Muslims. 
A very stressful part of the St. Catherine's Monastery is the Ossuary - a place dotted with skulls and various bones, as well as a skeleton of Stefan, who was a guardian of the Mount Sinai trail.
