St. George's Monastery - Wadi Qelt
St.George's Monastery is an ancient retreat hollowed out of the sheer rock wall in the deep and narrow Wadi Qelt gorge. The monastery was founded in 480CE around a cluster of caves where, according to tradition, St. Joachim learned from an angel that Anne, his sterile wife and mother-to-be of the Virgin Mary, had conceived.
In 614CE invading Persians massacred the monks and destroyed the monastery. It was partially reoccupied by the Crusaders in the Middle Ages but only fully restored at the end of the 19th century. Some attractive 6th-century mosaics remain, and there is a Crusader-era church with a shrine containing the skulls of the martyred monks.
