In AD 95, during the emperor Domitian's persecution of Christians, St. John the Theologian was banished to Patmos, where he lived until his reprieve two years later. He writes that it was on Patmos that he "heard … a great voice, as of a trumpet," commanding him to write a book and "send it unto the seven churches." According to tradition, St. John wrote the text of Revelation in the little cave, the Sacred Grotto, now built into the Monastery of the Apocalypse.
The voice of God spoke through a threefold crack in the rock, and the saint dictated to his follower Prochorus. A slope in the wall is pointed to as the desk where Prochorus wrote, and a silver halo is set on the stone that was the apostle's pillow. The grotto is decorated with wall paintings from the 12th century and icons from the 16th.
The monastery, which is accessible via several flights of outdoor stairs, was constructed in the 17th century from architectural fragments of earlier buildings, and further embellished in later years; the complex also contains chapels to St. Artemios and St. Nicholas.
