On the other side of the hill from St Paul monastery there is a cave where the hermit Antonius lived more than 1600 years ago. The cave is 680 meters above sea level; A staircase with around 1,000 steps leads to this hollow. As you climb up to the cell of the saint, you can see scriptures and drawings - and when you look outside, you have a fantastic view of the mountains and the desert. Immediately after the death of the ascetic in 356 AD, Christian monks founded the monastery of St. Antonius at the foot of Antonius Mountain. This monastery is considered the beginning of Christian monasticism because it served as a model for believers throughout the Christian world. Nowadays it houses more than 100 monks. It covers a huge area of ​​6 hectares, which is surrounded by a wall that is around 1,200 meters long and 12 meters high. Here you will find an old Coptic church where the holy man is buried and well-preserved medieval paintings. His library contains valuable ancient manuscripts.
